HI ALL
-----
I have a fundamental question:
What is the best way to perform Matrix-Calculation in VB.NET?!
I want to know what is the fastest way to do that?!
-----
Let me explain it more:
I want to do some processing on images,
(For example: Apply a gaussian-filter on a gray-image),
So, i must write a code that calculates the convolution of two matrices, because:
FILTERED-IMAGE = result of convolution of IMAGE and FILTER
And it is obvious that:
IMAGE = H*W matrix,
FILTER = L*L matrix, and
FILTERED-IMAGE = H*W matrix
---
Now, the question is: How can I perform these Matrix-Calculations in VB.NET?!
I think it can be done in this manner: "Modeling each matrix with a 2-d Array"
Is it correct?!
If yes, is it a fast way to work with image matrices?!
If no, what is the best way?!
-----
PLEASE GUIDE ME...
THANKS ALL

5. Yes it is a way but native code is still more performant ;)

Hello Bruno,
I fully agree: speed and .Net are a contradiction.
If speed is relevant, an in-depth evaluation of various technologies should be conducted. Speed requirements are relative. The question is: is the provided performance good enough ;-)

Yes of course the question is: is it good enough. Either way I'm keen on get the last from it (it==hardware) ;)
