Hi, I have a cell variable that looks like this:
I'D like to know if there is a way to transform it into a matrix of this kind:
NewVar=[2 5; 2 3; 2 5];
Thanks

tmp = {'002,005';'002,003';'002,005'};
NewVar = cell2mat(cellfun(@(S) sscanf(S, '%f,%f').', tmp, 'uniform', 0));

Efficient solution:
>> C = {'002,005';'002,003';'002,005'};
>> sscanf(sprintf('%s;',C{:}),'%f,%f;',[2,Inf]).'
ans =
2 5
2 3
2 5

tmp={'002,005';'002,003';'002,005'};
NewVar=str2double(split(tmp,','))

When I run this I get 'Undefined function 'split' for input arguments of type 'cell'. I'm using Matlab 2015, maybe that split function isn't available for my matlab version.

strsplit might work, but you might need to loop over cells
