fwhm

Compute the full width at half maximum

Syntax

fwhm_val = fwhm(f, x)
fwhm_val = fwhm(f, x, plot_fwhm)

Description

fwhm calculates the Full Width at Half Maximum (FWHM) of a positive 1D input function f(x) with spacing given by x.

For example, running the code

x = -pi/2:pi/20:pi/2;
f = cos(x); 
fwhm(f, x, true);

produces the output

Inputs

f

f(x)

x

x data or dx

Optional Inputs

plot_fwhm

Boolean controlling whether a plot of the function and FWHM is produced

Outputs

fwhm_val

FWHM of f(x)
