So I have a dataset with all the elements/answers being: 'A1 A2 A3 A4'. I need to transform those elements into '1, 2, 3,4'. Basically I just need to get rid of the 'A'. I have been trying this > Mydata=cellfun(@(x)x(2),Mydata); Im trying to extract the second element only (1,2,3,4) for the whole dataset but I get the followign error:
Index exceeds the number of array elements (0).
Error in @(x)x(2)
The format is 'cell' (not table). I then need to apply a fuction to substract 1 to each element, so 1=0, 2=1, 3=2 and 4=3. If anyone could help me i would really appreciate it! I'm obviously very new to matlab.
