MATLAB: Adding a row to an unknown matrix – the row consists of the mean value of the columns of the unknown matrix.

Question

Add a row to the bottom of A that consists of the mean of each column of A and assign the resulting matrix to B.

I am trying to add a row into an unknown matrix – the row has to consist of the mean of the columns of the unknown matrix.

Does anyone have ideas?

Thank you,

Gabe

The last row of the matrix A is A(end,:). Then ask yourself: What would be the indexing of one row beyond "end"?
