I havea table on gui and fill 2 number 12500 and 12600 and saved as cell. When I convert it to matrix using cell2mat, if the two numbers don't have the same numebr of digits (12500 and 1250 for example) I get this error "Error using cat Dimensions of matrices being concatenated are not consistent.
Error in cell2mat (line 83) m{n} = cat(1,c{:,n});
Error in main3>pushbutton15_Callback (line 235) matbuildcost=cell2mat(buildcost)"
How should I do?
Thank you

Because that cell array actually contains strings, and does not contain numeric values. If the strings are of different lengths then they cannot be concatenated together vertically, thus the error. The easiest solution is to convert the strings to numeric values using str2double. If you want to keep the data in string form, then use char instead.
Lets have a look at an example:
>> X = {'12500';'1250'};
>> cell2mat(X)
Error using cat
Dimensions of matrices being concatenated are not consistent.
Error in cell2mat (line 84)
m{n} = cat(1,c{:,n});
>> str2double(X)
ans =
12500
1250

Please show exactly how you are generating your data, and upload the data in a .mat file.
