Please find the attached file which is a 625000x1 signal variable y(t) I also have time series t=0:dt:64-dt; which correspond to y(t) numerically.
if I need a nonlinear time transformation to make h(t)=sqrt(t.^2+const); const=3 sec for instance.
How do I extract y(h(t)) for t=0:dt:5 for instance? The length of the vector would be different from 625000x1 of course. Thank you!!
