Great Work..Thank you for sharing..:)

16 Nov 2013 Bessel Function of Complex Order and Argument Bessel function of complex order and argument Author: Hongxue Cai Mark T

Hi again, I needed to use this function intensively. By shifting the series summation into the mex file, one can gain significant speed-up (for my work, about 50x faster).

Many thanks for this.
Concerning the previous comment, it seems that the tolerance can be adjusted in cbesselj.m ('tol'). Still needs some tweaking to allow one to call the function with independent arrays for nu and x (i.e. both not scalar).

09 May 2013 DFT on a specified frequency spectral analysis (amplitude & phase) of recorded time-series data Author: Hongxue Cai know

it's usefull. But how to reconstruct the data?

Dear Hongxue Cai,

Thank you for your contribution and I would like to know how to use your GUI funciton since I am looking for a way to get the x and y coordinates of edge detected images(*.jpg).

Since I was new in this task and pls advise me. I am looking forward to hearing from you good news soon.

Thanks and best regards
