how to get the second variable in a function?

I'm passing the value for function par it accepts two input but the function gives only one output A_output = par(20,5). How can i get the more than one output parameters?

delete(gcp);
parpool('AttachedFiles',{'par.m','par2.m'})
  spmd
if labindex == 1
A_output = par(20,5);
labSend(A_output, 2);
else
       B_parameters = labReceive()
 B_output = par1(B_parameters)
 end
  end
%par.m
function[x,y] =par(x,y)
y=y+40
 x=x+y
 z=x+200
end
%par1.m
function[xb ,yb]= par2(yb)
 yb=yb+4
 xb=yb
 yb=xb+20
end

Very basic MATLAB concepts, such as how to get call fucntions and return their output arguments, is explained in the introductory tutorials:

https://www.mathworks.com/help/matlab/getting-started-with-matlab.html

These are highly recommended for all beginners, because they teach these very basic concepts which all users need to know in order to be able to use MATLAB.

Function concept ok. But when simultaneously running two mfile,fetching the output from the function is little bit confusing.

Function concept not ok. Neither call in the code has the second return variable on LHS of the expression; ergo the function will NOT return more than the one result.

I have struggled with the very basic simple concept, now only I am cleared. Thank you all for your suggestions!

Answer 1

[Torsten]

[A_output,B_output] = par(20,5);

And name input and output variables differently in par and par2.

Best wishes

Torsten.

eventhough,I have changed the input and output variable names different it is giving one output only.

Answer 2

[dpb]

[A,B] = par(20,5);

The function has to have somewhere to "put" the other output...

I can't get the answer.Kindly give some explanation.
