width = fwhm(x,y)
Full-Width at Half-Maximum (FWHM) of the waveform y(x) and its polarity.
The FWHM result in 'width' will be in units of 'x'
The code was developed by an unknown author.

Updates
| 1.0.0.0 | No need to reassign variables 'x' and 'y'. Remove last 'else' condition. |
|
1) Remove line:
2) Replaced two two "if-end" conditions by "if-else-end" condition 3) The output argument "c" was never returned, hence it has been removed. |

i have 5 pulse in my signal ...how to find FWHM for every pulse?
Thanks in advance

is there a reason why the widths come out negative?

Can this be extended to find out FWHM of multiple culrves in a single plot and compare between the FWHM? If so, how?

this code is not working for raised sine and raise cosine functions.

Add the following line to handle data with a narrow dynamic range (insert at line 12).
y = y - min(y); %need to subtract off minimum to span [0 1]

Great! Quite happy with it.

When I try to take columns out of my array into fwhm - e.g. fwhm(peak(:,1),peak(:,2)) - I am getting an error saying that max is undefined for 'datasets'. So there is an error in y = y / max(y).
Sorry, I have no experience with MatLab. Any help would be greatly appreciated!

I'm trying to use this on spectral data from FTIR and I'm getting the error " Attempted to access y(132); index out of bounds because numel(y)=131."
My data is 131 points. Can anyone help me figure out how to use this? I'm very inexperienced with Matlab

thanks a lot. Finally I have got the result.

Works as advertised, a great improvement over the simple algorithm for FWHM I was using.

Simple and easy to read. I modified it to search for the falling edge from the end of the array instead of from the peak because my pulses have high overshoot at the rising/falling edges.

very easy to use, thank you

Need to add y=y-min(x) at beginning to find fwhm of data not going to zero
It does not work for noisy y(x). It keeps saying the peak is an impulse.
Superb
easy to use
Fantastic! Im so glad I found this!
Great Job !
Very easy to use!
great job!
