            Hi All,
I have a question: I have a matrix
A=[10; 20; 30; 40; 50; 50; 60]
How can I reshape it in order to have a matrix (7x30) X 1 such that the first 30 values are A(1), the next 30 have value of A(2), and so on...
thanks
nikolas

        This is not a reshape it's a repmat:
repmat(A, 1, 30)

				Just to be nitpicking :D ... the first 30 values of A, retrieved by A(1:30) will be  [10 20 30 40 50 60 70 10 20 ...] because A is a column vector and Matlab stores values columnwise.

      B=mat2cell(repmat(A,1,30),ones(1,7),30)
type A{1} and the result will be 30 10's.

				You're on a version earlier than R2016b. You have to use bsxfun on earlier versions.
Not that it matters, since the answer has completely changed.
