Expanding the existing Matrix

Hello,

I have matrix 365 x 1, how can I expand the matrix into 8760 x 1 -> (365 times 24), replacing all the newly added numbers with every 24th number.

eg: matrix [2,4,5,2,3 .... ] -> [2,2,2,2,2,...,2,2,4,4,4,...,4,4,4,...and so on).

I would be really grateful for help

Use repelem or kron, e.g. where V is your input vector:

Z = repelem(V,24)

or

Z = kron(V,ones(24,1)) % adjust to suit V's orientation.
