Can you use the concatenation ability of MATLAB to combine a 3x4 and a 3x5 matrix?

If yes, how we can do this?

[A,B]
horzcat(A,B)
cat(2,A,B)

Did you try searching for this before asking? MATLAB has documentation which is very easy to search.

Answer 1

Yes you can, as long as the row or column dimensions matches.

A = zeros(3, 4)   % A 3x4 matrix
B = ones(3, 5)    % a 3x5 matrix
AB = cat(2, A, B) %Concatenate along column dimension (dim = 2), resulting in a 3x9 matrix
AB = [A B]        %Same thing as cat(2, A, B)

Answer 2

Simply use square brackets, as you would use for combining scalars into a vector:

A = ones(3,4);

B = zeros(3,5);

AB= [A B];
