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')

Answer 2

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.
