I have a vector of 105 elements where the sizes are not compatible for a matrix. I want to make it a 2 dimensional matrix by adding zeros at last so that it becomes compatible for the matrix. Would you please tell me how can i do it?

If, e.g., 200 is the desired size, just use
vec(200) = 0;
All values between 105 and 200 will be filled with zeros.

Hello, use the reshape command.
Consider that your matrix has to be m x n (rows x columns) = total number of elements. Then do what Thorsten says vec(totalNumberOfElements) = 0, then
Matrix = reshape(vec,m,n).
Remember that rows run faster than columns... That is, the elements will be ordered in a row fashion way.

If you want a 100x2 from a 105 element vector, padding with zeros, this should do it:
buffer(1:105,100)
