hi , iam trying to find the FWHM for every peaks i have found , if you can help me to find FWHM for every peaks in the following graph in the following code when you run it that would be great

clc; close all; close all;

load instru.txt

channels = instru(:,1);

totcounts = instru(:,2);

%plot(channels , totcounts)

%time = 'insert the time ';

%T = input(time)

totcounting = totcounts/120;

%SOLIDangle = ' insert the solid angle';

%angle = input(SOLIDangle)

x1= 95;

x2 = 530;

y1= 0.24;

y2 = 1.33;

m=(y2 - y1)/(x2 - x1);

b=(y1-m*x1);

for V= 1 : size(channels)

    enrgy = m*channels + b;

end

data= [enrgy,totcounting];

[pks,location]=findpeaks ( totcounting,enrgy )

findpeaks ( totcounting,enrgy ) -------------------------------------------------------------

instru file :- save it as text and name it instru in the attachment
