I want to compare two matrices for that the number of rows and columns should be similar
The two matrices to be compared are as follows
A=[3 4 5; 3 4 5; 3 4 5]
B=[1 2 3 4 5 ; 1 2 3 4 5; 1 2 3 4 5]
Consider the numbers also as their position in the matrix for ease of understanding
That means we need two rows and two colums of zero at the start
the expected matrix of is as follows
A=[0 0 3 4 5;0 0 3 4 5;0 0 3 4 5]
P.S. The number of colums and rows of zero are not always the same. that could be varying like 3 colums and 1 rows and further

A = padarray(A,[abs(size(B,1)-size(A,1)) abs(size(B,2)-size(A,2))],0,'pre') % requires image processing toolbox
Gives:
A =
0 0 3 4 5
0 0 3 4 5
0 0 3 4 5

Did you try my answer?
n=2; % no of zeros(rows & columns) to be padded
A=[zeros(n,size(B,2));zeros(size(A,1),n) A]
Gives:
A =
0 0 0 0 0
0 0 0 0 0
0 0 3 4 5
0 0 3 4 5
0 0 3 4 5
