Concatenating a range of variables into a 3D array

I need to concatenate a range of variables into a 3D array. I have loaded my csv files into my workspace and can concatenate the data using "MyArray = cat(3, x1, x2, x3);" where x1,x2,x3 are the names of the variables

This gives the array structure I require however I have 100 csv files i.e. x1,x2,.....,x100 and I would like specify the range of variables rather than actually entering all 100 variables.

example

x1=10;
x2=20;
x3=30;
x4=40;
eval(['cat(3' sprintf(',x%d',1:4) ')'])

But the problem is, how did you come up to all those variables, when it's possible to use just one variable containing all your data.

Thanks for the answer. I didn't explain properly that each of these variables is actually a 186 rows by 61 columns. x1, x2, etc is just the name of the variable.

This is not important

Thank you Azzi, that works perfectly. The actual code I used is below:

MyArray = eval(['cat(3' sprintf(',x%d',1:100) ')'])

size (MyArray) returns 186 61 100 which is absolutely correct
