Convert cells arrays into a matrix

I have Norm matrix (well I believe). This matrix is made of made different matrices coming from samples ECG samples. Each of the array inside has only one vector of different size when I try to convert into a csv file, i have the following message :' The input cell array cannot be converted to a matrix.' here is the

    % code

 csvwrite('Norm.csv', Norm)

however, when I try try it to one array or vector of the matrix it odes work.

if true
  csvwrite('Norm.csv', Norm{1})
end

How can i get the whole matrix on a csv format

csvwrite does not accept cell arrays and you cannot simply use cell2mat because your vectors have different number of rows. One way would be to pad the shorter vectors with NaNs. Here's a FEX function that does exactly that:

Downside is that you end up with a bunch of NaNs in your output csv.
