Thanks for the sudden reply. I tried that but what it is not "splitting" the dataset into different arrays, instead giving the same data set in each new array, which is not I wanted. I made some confusion in the question, i think. What i require is to split a large array, say array(1000) to arrays(100), in which i will be getting first 100 points in the first column then the next 100 in the 2nd column and so on. but that is not happening with the reform command?
Did I do anything wrong?
