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

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.

This should be a new Question.
b = myRand
function a = myRand
a = 10*rand(3,4);
end
That said, it works for me, so problem solved!

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