end 

Answer 1

[Walter Roberson]

ca is a cell array. The first n entries of the cell array are to be reshaped into vectors and stored as columns of M. You would get an error if the number of elements in each entry is not the same.

In some cases, the code could be replaced with a call to cell2mat(), depending on what the shape of the entries is.
