Live Fourier transform
During some recent presentations, I have used a small matlab program giving me a live Fourier transform of the laptop camera input. It can be used in combination with some printed “structures” to show what we would see on a SAXS or WAXS detector. The idea is not mine, I heard that it was used [...]
Monte-Carlo Code
Hi all, Herewith a preliminary release of the Monte-Carlo code for fitting SAXS patterns. Documentation will follow, as will a movie and more. MCFit_sph.m Check it out and let me know if you have any questions.
Sorry for the delay
Hi all, Sorry for the big wait. It is not over yet, but I am working on it. More posts hopefully soon although I cannot promise a topic. Might be videos, but maybe also the monte-carlo code. The Monte-Carlo thing is almost ready to go, just some documentation left to write. It has become a [...]
saxsfit software with documentation, fitting function examples and example data
Hi all, I have made some new software available on the “software” page. This is the saxsfit (yes, terrible name, I know) routine I normally use for fitting SAXS curves to model functions. Nothing special, except that it can also deal with (time)series quite nicely. Also there is documentation for some of the packages. I [...]
“Perfect” 1D pattern generation software.
I have written some small, simple bits of Matlab software that can generate scattering patterns in the range you request for polydisperse, dilute spheres or ellipsoids. While nothing new per se, this implementation is guaranteed to produce correct scattering patterns irrespective of the width of the distribution. Allow me to quickly explain. The normal way [...]
