How to combine multiple random matrix.

Need hepl please.

Here is given code where I am generating binary matix based on switch case. I want to "repmat" to generate final matrix.

for example:

In case 1 c1 matrix is generated and in case 2 c2 matrix generated and so on.

If c1, c2 and c4 matrix are generated. how i can "repmat" them using general command.

same as if c2 and c3 generated then without changing in code it should "repmat" c2 and c3.

If my question is not clear please let me know. I will explain more detail. Thanks

            id3 = find (sum3<x3 | sum3==x3);
            c3=c3(id3,:);

        case 4
            %%OR Group Mandatory
            x4=input('OR group Mandatory features number: ');

            id4 = find (sum4>0);

I think you should add more detail. I don't understand the question. What do you want the size of the final matrix to be relative to the size of the c1, c2, c3, and c4 matrices?
