Description

Parentheses () specify order of operations, perform indexing, and enclose function and method input arguments. For instance, (A.*(B./C)) uses parentheses to specify order of operations.

Examples

Operation Precedence

Use parentheses to explicitly specify order of operations in long or complicated expressions.

a = 5;
b = 4;
c = 8;
d = 2;

(a.*(b+c))./d

ans = 
30

Parentheses Indexing

Create a matrix and index the first element, first row, and first column.

A = [10 1 1; 1 10 1; 1 1 10]

A = 3×3

    10     1     1
     1    10     1
     1     1    10

A(1,1)

ans = 
10

A(1,:)

ans = 1×3

    10     1     1

A(:,1)

ans = 3×1

    10
     1
     1
