Baseline Fit each column in "x". There did not seem to be a similar function in th file exchange. This routine is simply a wrapper for two Matlab routines, interp1 and ginput. Syntax: [ycorr,yfit] = bf(y,pts,avgpts,method,confirm); ycorr = bf(y); ycorr = bf(y,method); A baseline fit is interpolated from selected points and then applied to the data.

This program calculates the beats per minute of of an ECG signal. The data file should be in 'csv' format. The output will be an averaged value, since normal ecg of a person is not always constant. There maybe drifts and variations. The percentage error for six seconds of the ecg will be 60/sampling frequency.

Compute the discrete Fourier transform at specified frequencies, not using fft. Why one may need this? (1) MATLAB fft function computes the amplitude of signals only (no phase). (2) Once having the recorded time-series data, one often uses fft to do the spectral analysis.

This function is written to understand and/or explain an fft algorithm and usage of radix2 procedure. This function take the signal which you want to find FFT, for m bit you can also call the function without entering a signal or number of points, because there is default values for y and m which are; y = sin(2*pi*50*t)+sin(2*pi*120*t); m=3; you can see the steps of order reversing used as built-in function but non others.
