Ran in:
If the contents of the cells cannot be concatenated into a matrix, then you'll get an error telling you so.
For example:
C = {[1 2]; 3}
C = 2×1 cell array
{[1 2]} {[ 3]}
cell2mat(C)
Error using cat
Dimensions of arrays being concatenated are not consistent.

Error in cell2mat (line 83)
m{n} = cat(1,c{:,n});
Is that the error you got?

Yes the error is:
Error using cat
Dimensions of arrays being concatenated are not consistent.
Error in cell2mat (line 83)
m{n} = cat(1,c{:,n});
And my cell is numeric, a single line with 198 numbers

Please show the output of
temp = cellfun(@size, YourCell(:), 'uniform', 0);
maxlen = max(cellfun(@length, temp));
sizes = cell2mat(cellfun(@(V) [V ones(1,maxlen - length(V))], temp, 'uniform', 0));
unique_sizes = unique(sizes, 'row')

If the cell contents are not numeric, then cell2mat() might refuse. In such a case, you can try
As_Matrix = cat(1, TheCell{:});
if you want to end up with a 198 x something array.
