[Nirfast] Nirfast Digest, Vol 22, Issue 1

Fri Jun 5 03:02:34 EDT 2020

Hi

Please start here:

https://github.com/nirfaster/NIRFASTer/blob/master/toolbox/common/get_solver.m

and then follow the ‘See also’ help section.

And this in general:

https://github.com/nirfaster/NIRFASTer

All the MATLAB help needed exist in there, including live MATLAB scripts.

Also run this from your MATLAB to check differences in solvers speed at your machine:

test_solvers_speed_and_accuracy.mlx

Cheers,

S.

Hi All,

Does anyone know what the units of the source in NIRFAST would be? Ex: photons/mm^3, J/mm^3 etc.

Thanks!

Hi Sandhya

It can be any unit you need. A source amplitude is equal to 1. Therefore, if
you decide that your source emits 123456 photons per mm^3 per second,
multiply your results by 123456 and it will be in your source unit. Do the
same with any unit you like.

In general, the NIRFAST result can be expressed as the photons fluence rate
in [mm^-3s^-1] and no 'photons', 'J' or 'W' is used as this is not needed.
The source is of amplitude 1 and photons, Joules or Watts simply scale the
result.
