Finding fwhm of a curve in python

WebOct 10, 2024 · 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. WebMar 24, 2024 · The full width at half maximum (FWHM) is a parameter commonly used to describe the width of a "bump" on a curve or function. It is given by the distance between points on the curve at which the function reaches half its maximum value. The following table gives the analytic and numerical full widths for several common curves. See also
