Ridge Regression Code error message

Dear,
I wrode the following comand for Ridge regression:
X = file name
x = [Crack];
y = FFT;
n = length(y);
c = cvpartition(23,'HoldOut',0.3);
>> idxTrain = training(c,1);
>> idxTest = ~idxTrain;
>> b = ridge(y(idxTrain),X(idxTrain),lambda);
The logical indices contain a true value outside of the array bounds. (I´ve got this message. What´s wrong ?)
Thanks for your support !

Hi,
From the code I think the cvpartition that is created should have ‘n’ number of observation instead of 23. That is why the logical vector generated by training has size mismatch compare to X or y. Changing 23 to ‘n’ should work.
