suppressing the display of ans

How can I suppress or omit the display of the "ans" when executing my function?

[John hebert]

To suppress 'ans' return of function file don't assign an output; find the variable and use disp(variable).

Tried this and it worked. Thanks John

thank you very much

I solved this issue by doing this (but I tried for one output only):

function a=myfunction(b)
%here is yor code
    if nargout<1
        clear a 
    end
end

[Abhiram V. P. Premakumar]

vmin=0.9737; 
vmax=1.0263;
disp('        vmin         vmax') 

        vmin         vmax

disp([vmin,vmax])

    0.9737    1.0263

When you enter a command without a semicolon at the end, MATLAB displays the result.

>> x = 5 + 1

x =

6

[Nikhanze]

Enter k = 8-2; including the semicolon at the end. The result won't appear in the command window,but you can see the value of k in workspace browser

It seems that the semi-colon is not the desired solution. If you can change the function, one solution is to use nargout and simply not define an output for nargout==0:

function x = temp
if nargout>0
    x = 2;
end
end

when called in the command window:

>> temp
>> x = temp
x =
     2

Some MATLAB functions do this, or have a look at calendar for a similar concept.

Put a semicolon at the end of the line.

x = randn(8,1);
fft(x);

[Pramod Bhat]

Dale is asking how to hide the word 'ans' when there are no arguments. for ex if u just type 2+2 on workplace it will display

ans=

4.

He does not want this 'ans' to be displayed.

[Wayne King]

The OP said he wants to suppress the "display" of ans, that's why I told the OP to put a semicolon at the end of the line:

>>2+2;

does what the OP asks as I answered.

[George Fega]

You are the best, dude! Thank you vrey much!

[Le Yu]

That's exactly what I need!! THx

Answer 3

[Matt Tearle]

What Wayne said. But to dig a bit deeper: given that you specifically said "function", I'm guessing you might be confused by the whole local vs global variable thing.

If you have

function y = myfun(x)
y = cos(x.^2);

Then you say

>> z = myfun(pi)

The value of pi is passed into the function where it is assigned to the local variable x; the value of the local variable y is computed and returned to the base workspace according to how the function was called at the command line. In this case, the return value is assigned to the (base) variable z. Because there's no semicolon at the end of that line, the output from that assignment is echoed to the command window. So if you call it as

>> myfun(pi)

MATLAB, as always, assigns the calculated value to ans. Again, there's no semicolon, so you see the result displayed. Note that this display has nothing to do with the line y = cos(x.^2); in the function. If you leave off the semicolon there, you'll see that assignment echoed to the command window -- y = -0.9027 -- and the assignment to ans as well -- ans = -0.9027.

If the function has no return values, nothing will be assigned to ans:

function myfun(x)
plot(x)

>> myfun(1:5)

A=5;

B=4;

z=A+B;

disp(Z)

Answer 5

[Pramod Bhat]

It is not possible. Where there are no arguments MATLAB automatically makes "ans" a variable and assigns value to it. You cant hide it.

[Walter Roberson]

Probably not correct. You can override the display() function, which is what is invoked to output a value when there is no semi-colon after an expression.

Answer 6

[Kenneth Cantos]

is there a code that can hide an output on the command window but the item to be hide will be needed on the succeeding formula.

for example:

i will set A=1+2 B=1+3

Formula:

Z=A+B

Z=9

I want to show only the result of Z.

thanks guys.

[Walter Roberson]

Like

Z=A+B;

?

Answer 7

[Niklas Berg]

If your output argument is called x for example just type

clear x

in the end of your function. Then x won't show as ans in the command window.

Answer 8

[Kavya]

When you enter a command without a semicolon at the end, MATLAB displays the result.

>> x = 5 + 1

x =

6

Optionally, you can add a semicolon to the end of a command so that the result is not displayed. MATLAB still executes the command, and you can see the variable in the Workspace browser.

>> x = 5 + 1;
