The first spacing value hx specifies the xspacing as a scalar or xcoordinates as a vector of the points. Help text appears in the command window when you use the help function.

The function initially removes the mean of x and adds it back after computing the envelopes. I want to fit, plot and generate a sinusoidal function to these data points. This example shows how to create a function in a program file. Such a plot of amplitude versus frequency may be called a spectral plot, or spectral representation of the complex sinusoid. Pure sine wave inverter design with code the engineering. This section provides matlaboctave program listings for the sinusoidal resonatoroscillator algorithms discussed above.
