Fwhm of normal distribution
Did you know?
In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y-axis which are half the … See more Normal distribution If the considered function is the density of a normal distribution of the form Other distributions In spectroscopy half the width at half maximum (here γ), … See more • Gaussian function • Cutoff frequency See more • FWHM at Wolfram Mathworld See more WebJan 3, 2003 · new_distribution = array * sigma + mean So if you want a Gaussian distribution with a mean of 50 and a sigma of 3.5, the you simply do this: sigma = 3.5 mean = 50.0 array = RANDOMN(seed, 1000) new_distribution = array * sigma + mean A distribution with these characteristics would have a FWHM calculated like this:
WebOct 10, 2024 · Accepted Answer. The fwhm function is a File Exchange contribution. As I read the function code, it should likely give you something other than NaN if it detects 2 edges, however I have no idea what youare passing to it. If you have the Signal Processing Toolbox, another option would be the findpeaks function.
