Hi,

Can you provide me a link or algorithm for multiplication of two sparse matrices using Linked Lists?
So that it will help me to better understand the logic and implement the program on my own.

Thanks!

No... but you can try it on your own and then come back here if you get stuck and have a real question.

Hi,

I dont have much idea about linked lists. Hence i wanted an algorithm that can help me to understand it so that i can implement the program on my own. I dont want readymade program. I wanted to try that my self. I just need th e understanding behind it.

Assuming this is for professional work, have a look at:
GSL CBLAS Library[^]
uBlas[^]
cublas[^]

Just out of curiosity, I've heard that the native 3D matrixes in the WPF enviroment stores the matrix vales with limited presition. Do you know why? And do they also use the GPU to calculate the transforms of view etc. ?

Im asking becouse I thought I might be able to use it in ray tracing in acoustics, but it seems rather complicated...

Haven't the foggiest notion about the precission thing - I'd go for nvidia cublas or intel MKL, I mentioned CBLAS and uBlas because the source is readily available. WPF uses the GPU, and I'd be surprised if transforms wheren't processed there too - but care has to be taken to avoid falling back on the software renderer.

Seems I have some research to do :)

You should start with Wikipedia, and what you are looking for is Matrix (multiplication, substraction, etc..):
