Hi, I have a matrix of 13x15 double. I want to do randomization by using the coding below to discard 1st coefficient of the data.
The coding: Random_new_data = newdata(2:end, randperm(30));% column 2 to 13
However I got the "index exceed Matrix dimension error"
May I know what is the possible problem in the data? Thanks a lot.

randperm(30) produces a vector ,including 1 to 30.
But your matrix's column is 15 .
So,it is possible that 'Random_new_data = newdata(2:end, randperm(15));'
