Calculate number of coefficients given error term Hi all, I m about to approximate a set of data (stock indizes) with its fourier transform. In order to be able to compare it with other data sets, I was thinking about calculating the needed coefficients (for the ifft) given a pre-specified error term between the estimator and the original data (e.g. by MAE). I onl... 14 Jun 2010 17:21

What I prefer to do in those cases is to then assign a dummy filehandle to the port variable such that any further calls to fwrite(... 14 Jun 2010 18:28
