Functions inputs/outputs

Question

Hi i've been coding with matlab for a while now and i ran into a problem with passing inputs to function from main.

For example :

function [cellAr] = MathematicalFunction()
%UNTITLED Summary of this function goes here
%   Detailed explanation goes here
x = randi([-10,10] , 1,50);
y = randi([-10,10] , 1,50);
disp(x);
[xx,yy] = meshgrid(x,y);
z = sin(sqrt(xx.^2+yy.^2));
cellAr = {xx , 'x' , yy , 'y' , z , 'z'};
end

i wrote this code to make a meshgrid out of 2 random vectors and calculated a z axis.

For the next step i wanted to make another new function to plot the 3D graph. So i created a new void function that receives 2 inputs both are being sent from the main script and i was unable to send the cellAr and another input from the main script as new inputs to the 3D plot function to use and there were two problems that i couldn't solve :

1) "Too many output arguments". How can i have too many output arguments in a void function?

2)i was unable to send the newly generated cellAr and another string input to my Plot3 function through my main script.

my main looks like this :

clear clc
Array32 = MathematicalFunction();
ThreeDim = Plot3D(Array32,'surfc');

This isn't the first time i have a problem passing elements from main to another function so i must be doing something wrong.

Please show us the code you wrote for the Plot3D( ) function.

This is my plot3D function :

function Plot3D(Array32 ,str)
%UNTITLED3 Summary of this function goes here
%   Detailed explanation goes here
switch str
    case surfc
        surfc(Array32(1),Array32(3),Array32(5))
        disp('surfc')
    case surf
        surf(Array32(1),Array32(3),Array32(5))
        disp('surf')
    case contour
        contour(Array32(1),Array32(3),Array32(5))
        disp('contour')
    otherwise
        disp('non')
end
end
