How to merge multiple matrices

I need to combine multiple matrices (doubles) (all the same length with padding of 0) into one matrix without losing their 'position'. The problem is when I do that, it seems that the numbers physically add in the one matrix rather than just become one matrix retaining all of the individual numbers. How would I combine all these matrices together? The end result is that I will need to plot this set of combined matrices with another set of combined matrices

Can you give a small example or two of input and output matrices that illustrate how you want them combined?

[Jason Moore]

x = ones(5,5) y = zeros(5,5) z = [x,y]

Z will end up being a combined matrix with a dimension of 5x10

A "matrix" is a 2-D array. What do you mean by the "length" of a matrix? What do you mean by padding? Can you give a numerical example?

I've attached two examples of doubles I want to combine into one double. Image: you can also take a look at my previous question http://www.mathworks.com/matlabcentral/answers/264290-need-to-combine-doubles-with-different-sizes

One option is to use the cat function.
