Hi Matlab community,
Here's another newbie question. I would like to replace the 6th column with the first 5 digits of that column (20134); I would then like to create a 7th column that is the last digit of the 6 column. Here's a sample array.
Thank-you for your help.
cell = {'this' 'is' 'a' 'cell' 'array' '2013420134' }

C = {'this' 'is' 'a' 'cell' 'array' '2013420134' }
V = C{6} % retrieve the 6th cell
C{6} = V(1:5) % replace it
C{7} = V(end) % add a new cell
btw, avoid giving your variable the same name as a matlab function

Thanks Jos for showing the alternative. Thanks for pointing out my ridiculous variable name, picked it quick for the example.
I basically ended up using a loop since there are close to 17000 variables
[m,n]=size(data); for i = 1:m data1{i,9} = data{i,9}(1:5); data{i,9} = {}; data{i,9} = data1{i,9}; end
Just having fun in matlab on a sunday night :)
