How to divide a data set into training and testing data set in MATLAB using cross-validation?

Question

Hello guys, how could I divide a clinical dataset into training and testing datasets using cross-validation?

Have you looked this ?

Apart from that, do you have to use just MATLAB, you can find more help or documentation if you use python or R.

@arta yes, I already checked that link but didn't get what i want. My data is a matrix of 359 rows and 5 columns but when i applied that code on the link you proposed i got 2 datasets but with only one column on each.However, my goal is to find 2 subsets of training and testing sets with random rows but 5 columns I'm more familiar with MATLAB.

My inputs were a matrix of 359*5

My expected outputs

• training set: k*5
• Testing set; l*5

Well, technically it should work. Quick and dirty solution can be transposing the data before applying the function or you can check this link that i have found.
