[Help-gsl] spectrogram analysis ? |

Hello,
i need to analyze a set of data coming from a linear ccd Sensor via a
microcontroller. Therefore i have to find the peaks and the area under the
peaks as well as the average noise level.
A spline interpolation and its derivative on this data works nice .
I presume the integration will also work to find the areas,
but i do not know how to get the zeropoints from the
1st derivative " gsl_spline_eval_deriv" results to determine the peaks.
How to find the zero points ?
Is there a peakfinder on a dataset known ?
Is there an example sourcecode known which handle this problem ?
cheers wally
