Where can I find source code for scientific programs?

AI Thread Summary
The discussion centers on the search for existing programs similar to GSL, specifically for solving the time-dependent Schrödinger Equation, referencing a well-cited paper from the 1980s by Feit, Fleck Jr., and Steiger. The challenge highlighted is the difficulty in locating old source codes for such methods. It is suggested to contact the corresponding author of the original paper for access to the code, especially if it is not freely available. Additionally, a resource link to the Computational Chemistry List (CCL) is provided as a potential avenue for finding these programs.

:rolleyes: ... not sure if this is the right place to post this.

Hi, I'm looking for something like GSL but with programs instead of routines.

For example, there is a method that was developed in the 80's for solving the time-dependent Schrödinger Equation (M. D. Feit, J. A. Fleck Jr. and A. Steiger. J. Comput. Phys. 47, 412 (1982)). This paper has something like 1200 citations, so I'm sure many people have programmed it before.

Is there any place where I can found this kind of programs?

Thanks!

Hello,
it is difficult to get such old source codes. Better ask the corresponding author directly, if it not a free one.
Otherwise try here. May be you can get it.

Thread 'Learning Assembly and computer architecture for x86'

Dear Peeps I have posted a few questions about programing on this sectio of the PF forum. I want to ask you veterans how you folks learn program in assembly and about computer architecture for the x86 family. In addition to finish learning C, I am also reading the book From bits to Gates to C and Beyond. In the book, it uses the mini LC3 assembly language. I also have books on assembly programming and computer architecture. The few famous ones i have are Computer Organization and...

Thread 'Learning data structures and algorithms in different programming languages'

I have a quick questions. I am going through a book on C programming on my own. Afterwards, I plan to go through something call data structures and algorithms on my own also in C. I also need to learn C++, Matlab and for personal interest Haskell. For the two topic of data structures and algorithms, I understand there are standard ones across all programming languages. After learning it through C, what would be the biggest issue when trying to implement the same data...
