https://www.isical.ac.in/~malay/Papers/Conf/PerMIn12__print%2520copy.pdf indicates that they implemented in MATLAB.

The original paper on Ripplet-II transform contains a buried hint that it was developed in MATLAB.

Hi Jaya and Walter,

Thanks for your message. Actually I joined in corporate world and lost all this type of link. Extremly sorry for replying late. Please mail me in details, I will share the matlab code which I have developed during my PhD.

@Walter thanks for following my work.

Best Regards

Hi, can I get the link of ripppet transorm.

Please note, it is quite an old post. You may create the question as new one, as numerous functions has been added since 2014.

Hi, I am a student doing my work using the discrete ripplet transform. Can you help me with the DRT algorithm or DRT matlab code?

[Asma Kh]

Thanks a lot for the reply, but I can't find the "fun-comput-DRT" file.

[Walter Roberson]

@Asma Kh

I do not find any references to a file by that name anywhere; not sure why you expect to need it?

Note that MATLAB source code would not use a file by that name; fun_comput_DRT would be more likely (but I do not see any references to that either.)

Hi,thanks for reply,This file is called in %forward Discrete Ripplet Transform

[Walter Roberson]

@Asma Kh which source code are you looking at?

If you are looking at the source code provided by @Manish Chowdhury then you should be asking Manish

Hi, thanks for reply about discrete ripplet transform,

There is a file called "Com_featureMatrix_RT" that calls a function named " fun_compute_DRT()", But this function does not exist. Can you help me? Thank you very much
