Transferring waves into a matrix

Hello,

I created a matrix of with the number of rows= N and columns = 7 (root:matrix).

I have 7 different waves (all having length =N) in 7 different folders (root:A140:wave1; root:A141:wave2.... etc).

I would like to transfer each of these waves into this Matrix.
Is there some code that exists to do this?
For now I am doing this by hand but I need to repeat this exercise several times :-/

Thank you very much
Try the Concatenate operation as in:
Concatenate {wave1,wave2,... wave7}, newMatrixWave
