The 
Create a function handle to a named function: fhandle = @myfun Create a function handle to an anonymous function: fhandle = @(x,y) x.^2 + y.^2;

Period or dot 

The period character separates the integral and fractional
parts of a number, such as 
Decimal point: 102.5543 Elementwise operations: A.*B A.^2 Structure field access: myStruct.f1 Object property specifier: myObj.PropertyName 
... 
Dot dot dot or ellipsis 
Line continuation 
Three or more periods at the end of a line continues the current command on the next line. If three or more periods occur before the end of a line, then MATLAB ignores the rest of the line and continues to the next line. This effectively makes a comment out of anything on the current line that follows the three periods. NoteMATLAB interprets the ellipsis as a space character. Therefore, multiline commands must be valid as a single line with the ellipsis replaced by a space character. 
Continue a function call on the next line: sprintf(['The current value '... 'of %s is %d'],vname,value) Break a character vector up on multiple lines and concatenate the lines together: S = ['If three or more periods occur before the '... 'end of a line, then the rest of that line is ' ... 'ignored and MATLAB continues to the next line'] To comment out one line in a multiline command, use
y = 1 +... 2 +... % 3 +... 4; However, this code runs properly since the third line does not produce a gap in the command: y = 1 +... 2 +... ... 3 +... 4; 
, 
Comma 
Separator 
Use commas to separate row elements in an array, array subscripts, function input and output arguments, and commands entered on the same line. 
Separate row elements to create an array: A = [12,13; 14,15] Separate subscripts: A(1,2) Separate input and output arguments in function calls: [Y,I] = max(A,[],2) Separate multiple commands on the same line (showing output): figure, plot(sin(pi:0.1:pi)), grid on 
: 
Colon 

Use the colon operator to create regularly spaced vectors,
index into arrays, and define the bounds of a

Create a vector: x = 1:10 Create a vector that increments by 3: x = 1:3:19 Reshape a matrix into a column vector: A(:) Assign new elements without changing the shape of an array: A = rand(3,4); A(:) = 1:12; Index a range of elements in a particular dimension: A(2:5,3) Index all elements in a particular dimension: A(:,3)
x = 1; for k = 1:25 x = x + x^2; end 
; 
Semicolon 

Use semicolons to separate rows in an array creation command, or to suppress the output display of a line of code. 
Separate rows to create an array: A = [12,13; 14,15] Suppress code output: Y = max(A); Separate multiple commands on a single line (suppressing output): A = 12.5; B = 42.7, C = 1.25; B = 42.7000 
( ) 
Parentheses 

Use parentheses to specify precedence of operations, enclose function input arguments, and index into an array. 
Precedence of operations: (A.*(B./C))  D Function argument enclosure: plot(X,Y,'r*') C = union(A,B) Indexing: A(3,:) A(1,2) A(1:5,1) 
[ ] 
Square brackets 

Square brackets enable array construction and concatenation, creation of empty matrices, deletion of array elements, and capturing values returned by a function. 
Construct a threeelement vector: X = [10 12 3] Add a new bottom row to a matrix: A = rand(3); A = [A; 10 20 30] Create an empty matrix: A = [] Delete a matrix column: A(:,1) = [] Capture three output arguments from a function: [C,iA,iB] = union(A,B) 
{ } 
Curly brackets 
Cell array assignment and contents 
Use curly braces to construct a cell array, or to access the contents of a particular cell in a cell array. 
To construct a cell array, enclose all elements of the array in curly braces: C = {[2.6 4.7 3.9], rand(8)*6, 'C. Coolidge'} Index to a specific cell array element by enclosing all indices in curly braces: A = C{4,7,2} 
% 
Percent 

The percent sign is most commonly used to indicate nonexecutable text within the body of a program. This text is normally used to include comments in your code. Some functions also interpret the percent sign as a conversion specifier. Two percent signs, 
Add a comment to a block of code: % The purpose of this loop is to compute % the value of ... Use conversion specifier with
sprintf('%s = %d', name, value) 
%{ %} 
Percent curly bracket 
Block comments 
The NoteWith the exception of whitespace characters, the

Enclose any multiline comments with percent followed by an opening or closing brace: %{ The purpose of this routine is to compute the value of ... %} 
! 
Exclamation point 
Operating system command  The exclamation point precedes operating system commands that you want to execute from within MATLAB. Not available in MATLAB Online™. 
The exclamation point initiates a shell escape function. Such a function is to be performed directly by the operating system: !rmdir oldtests

Single quotes 
Character array constructor 
Use single quotes to create character vectors that have class

"" 
Double quotes 
String constructor 
Use double quotes to create string scalars that have class

Create a string scalar: S = "Hello, world" 
N/A 
Space character 
Separator 
Use the space character to separate row elements in an array constructor, or the values returned by a function. In these contexts, the space character and comma are equivalent. 
Separate row elements to create an array: % These statements are equivalent A = [12 13; 14 15] A = [12,13; 14,15] Separate output arguments in function calls: % These statements are equivalent [Y I] = max(A) [Y,I] = max(A) 
~ 
Tilde 

Use the tilde symbol to represent logical NOT or to suppress specific input or output arguments. 
Calculate the logical NOT of a matrix: A = eye(3); ~A Determine where the elements of A = [1 1; 0 1] B = [1 2; 3 2] A~=B Return only the third output value of
[~,~,iB] = union(A,B)

Equal sign 
Assignment 
Use the equal sign to assign values to a variable. The syntax
NoteThe 
Create a matrix A = [1 0; 1 0]; B = A; B(1) = 200; 
Some special characters can only be used in the text of a character vector or string. You can use these special characters to insert new lines or carriage returns, specify folder paths, and more.
Use the special characters in this table to specify a folder path using a character vector or string.
Symbol  Symbol Name  Role  Description  Examples 

 Slash and Backslash 
File or folder path separation  In addition to their use as mathematical operators, the slash and backslash characters separate the elements of a path or folder. On Microsoft^{®} Windows^{®} based systems, both slash and backslash have the same effect. On The Open Group UNIX^{®} based systems, you must use slash only.  On a Windows system, you can use either backslash or slash: dir([matlabroot '\toolbox\matlab\elmat\shiftdim.m']) dir([matlabroot '/toolbox/matlab/elmat/shiftdim.m']) On a UNIX system, use only the forward slash: dir([matlabroot '/toolbox/matlab/elmat/shiftdim.m'])

Dot dot 
Parent folder 
Two dots in succession refers to the parent of the current folder. Use this character to specify folder paths relative to the current folder.

Asterisk 
Wildcard character 
In addition to being the symbol for matrix multiplication, the
asterisk Wildcards are generally used in file operations that act on
multiple files or folders. MATLAB matches all characters in the name exactly except
for the wildcard character

There are certain special characters that you cannot enter as ordinary text.
Instead, you must use unique character sequences to represent them. Use the symbols
in this table to format strings and character vectors on their own or in conjunction
with formatting functions like compose

. For more information, see Formatting Text.
