Hi!

I would like to use IDL/ENVI to classify some data using SVM. Let's say I have 100 training samples, with 3 features each, like this:

seed = 123
xTR = RANDOMU(seed,3,100)
yTR = xTR[1,*] GT 0.5

and want to classify some test samples
xTE = RANDOMU(seed,3,100)

An option in IDL/ENVI seems to be ENVI_SVM_DOIT.
http://www.exelisvis.com/docs/ENVI_SVM_DOIT.html

Please, do you have suggestions how to pass my tabular data to ENVI_SVM_DOIT programmatically given that I do not have images/ROIS as input, and my IDL skills are still limited?

Thanks in advance!
