Curve Fit

Calculate and plot BER curve against SNR for BPSK Modulation in Gaussian Environment.It calculates 100 errors to Calculate BER for every SNR value to ensure better approximation.I hope that this help students of signal processing and communications...

This is the fastest (though not most accurate) method of fitting a circlle to data points on a plane (given by their xy-coordinates). It returns the circle center (a,b) and radius R. It was proposed by I. Kasa in article "A curve fitting procedure and its error analysis", IEEE Trans. Inst. Meas.,...

This is a fast non-iterative ellipse fit, and among fast non-iterative ellipse fits this is the most accurate and robust.It takes the xy-coordinates of data points, and returns the coefficients of the equation of the ellipse: ax^2 + bxy + cy^2 + dx + ey + f = 0,i.e. it returns the vector...
