Error: Too many output arguments

Hi. In my main M script I have:

 x = 0:50;

 y = 0:50;

 [X,Y] = meshgrid(x,y);

 P = P_fn(X,Y);

in my function I have:

 function P_fn(x,y)

 P = <some equation involving both terms x and y>

 end

when I run it I get the error:

>> P = P_fn(X,Y);

Error using P_fn

Too many output arguments.

Can functions only output one calculation and output? My equation works just fine if I use it in the main M script.

Thanks for reading

The error is because you did not define the function with outputs.

Try this:

 function P = P_fn(x,y)

 P = <some equation involving both terms x and y>

 end

Thanks. That works now. The reason I omitted it is because I wanted to be able to have the output displayed in the Command Window as P = answer rather than ans = answer. There doesn't seem to be any other way to get rid of the "ans = " part of the displayed answer.

My pleasure.

You can still have ‘P’ display to the Command Window by simply removing the semicolon from the end of this line:

P = P_fn(X,Y)

Please help me with my problem :

function a = myRand

a = 10*rand(3,4);

end

--------------

When I ran it

myRand ( it shows up)

Then I want to assign the result to a variable b :

b = myRand

And there is an error :

Error using myRand

Too many output arguments.

@Hadjer BEN BRAHIM —

This should be a new Question.

b = myRand

b = 3×4

1.4722 0.2712 7.6027 8.2860 4.9290 5.6392 1.6085 8.6403 8.9170 5.5582 5.6037 7.0630

function a = myRand
a = 10*rand(3,4);
end

That said, it works for me, so problem solved!

Mi función es la siguiente:

y a la hora de ejecutar, en un scrip:

me aparece el error:

¿Porqué?

[Star Strider]

The ‘f’ function does not return anything, although the anonymous function within it does.
