Given a N element data vector representing the output from the solution yH(t) of the homegeneous dierential equation dyH(t) dt + λyH(t) = 0 yH(0) = K Perform an Mth order regession to determine an approximate function yreg(t). Evaluate yreg(t) for a given input vector M. Approximate dyreg(t) dt using a backward dierence.
