Error- simple matlab function

I have the following function;

function [epsilon,sigma] = concatenatingAllDataSets(total_sets,X,Y)
epsilon = reshape(X,total_sets,[]);
sigma = reshape(Y,total_sets,[]);

I'm kind of very new to matlab but not to programming of course.

I get the following error;

??? Input argument "X" is undefined.

Error in ==> concatenatingAllDataSets at 3
epsilon = reshape(X,total_sets,[]);

??? Input argument "X" is undefined.

Error in ==> concatenatingAllDataSets at 3
epsilon = reshape(X,total_sets,[]);

??? Input argument "X" is undefined.

Error in ==> concatenatingAllDataSets at 3
epsilon = reshape(X,total_sets,[]);

I know I need to define the argumants.Can someone help?

Try the following:

X=[1:10];
Y=[11:20];
[a,b]=concatenatingAllDataSets(5,X,Y)

You need to define the arguments for X,Y and total sets either earlier or as inputs to the function..

THe output is:

a =
          1.00          6.00
          2.00          7.00
          3.00          8.00
          4.00          9.00
          5.00         10.00
b =
         11.00         16.00
         12.00         17.00
         13.00         18.00
         14.00         19.00
         15.00         20.00
