MATLAB: Get only one output from a function with several ones

functionoutput

Suppose I define a function:

function [A,B] = myfun(x,y,z)
...
...

I know that if I type

[C,D] = myfun(1,1,1)

then I'll get both C (corresponding to A) and D (corresponding to B) for the specific values or if I type

C = myfun(1,1,1)

I'll get C (corresponding to A). Is there a way to get only D for these specific values? Thank you in advance!

Yes. You need to use the ‘~’ (in English, tilde) to suppress the outputs you don’t want. So to get only ‘D’, call the function as:

[~,D] = myfun(1,1,1)

out = double(diff([~A(1);A(:)]) == 1);
v = accumarray(cumsum(out).*A(:)+1,1);
out(out == 1) = v(2:end);

out = zeros(size(A));
ii = strfind([0,A(:)'],[0 1]);
out(ii) = strfind([A(:)',0],[1 0]) - ii + 1;

If I get it right your function MatOb just prints x_values in the standard output. I fail to see the need of introducing one further variable "x". Anyway, if this is just a matter of standard output, you can use fprintf instead of disp

 fprintf('x = [%s]\n',sprintf('%1.3f ',x));

As I say, you can do this by using x_values in place of x.

Take a look at the documentation of fprintf and sprintf to get the hang of it.
