MATLAB: How to join two matrix arrays together

arraycell arraysmatrixmatrix manipulation

I have two matrices A(i) and B(i) with similar (i) arrays. This i will be vary in each run. For example for i = 3, A and B are:

A = [774 631 584];
B = [19 128 220];

I want matrix C to be:

C = [774,19;631,128;584,220]; % first array in matrix A comes with first array in matrix B

C=[A B]

sum(X(:)>100);

Horizontal concatenation

 c=[a b]

example

for horizontal concatenation

 a=rand(20,6);
 b=rand(20,3);
 c=[a b]

for vertical concatenation

 a=rand(6,20)
 b=rand(3,20)
 c=[a;b]
