Hello Manny Ram,
Let us consider Varibale A is having size of 16x30000 and B is having size of 9x1200
You can do this..
newRowLength = max(size(A,1),size(B,1));
newColLength = max(size(A,2),size(B,2));
if ((size(A,1)~=newRowLength) || (size(A,2)~=newColLength))
A(newRowLength,newColLength) = [0];
end
if ((size(B,1)~=newRowLength) || (size(B,2)~=newColLength))
B(newRowLength,newColLength) = [0];
end
Now A and B become of same length..

As per my given example..
The size of A and B will be now 16 x 30000
But this is the generic code, you can apply on any size of matrix, and it will give you the size of matrix as (greater number of row x greater no of column)
For example: If you have matrix C of 5 x 100 and D matrix of 10 x 50, then this code will give you new matrix C of size 10 x 100 and D also of size 10 X 100.
So that you can perform further operation.
