I have a curve data which:
x= (1:2^16) and y is a 1x2^16 matrix.
I want to create 9 more "y" data, by using bootstrap technique, that based on the initial y.
bootstat = bootstrp(nboot,bootfun,d); I wanted to use that function but I don't know what to write for "bootfun".

bootfun has to be empty using [ ]. then you just need the second output from bootfun [~,idx]=bootstrp(...) and idx contains n columns of index for n bootstrap sets, each column has the same number of entries as your original data. calling originalData(idx) will give you a bootstrap set in each column
