MATLAB: Combining 2 different sized matrices.

MATLABmatrices

I am trying to learn and practice some Matlab, this is one of the test yourself questions and I am just not able to understand how exactly I can do this. If anyone is able to explain I will appreciate it. Thank you

Best Answer

A = rand(3) ; 
B = rand(4) ; 
m = size(A,1) ; 
n = size(B,1) ; 
O1 = zeros(m,n) ; 
O2 = zeros(n,m) ; 
iwant = [A O1; O2 B] ;
OR
A = rand(3) ; 
B = rand(4) ; 
m = size(A,1) ; 
n = size(B,1) ; 
C = zeros(m+n) ; 
C(1:m,1:m) = A ; 
C(m+1:end,m+1:end) = B ;
