    How to accelerate the SVD algorithm?

    I dislike those who take themselves as industrious men. Is it a a great thing to develop sth on matlab?

    How to accelerate the SVD algorithm?

    I have to research linpack source code. It is more complicated than read the primitive document. Sigh.

    How to accelerate the SVD algorithm?

    So you know which algorithm Matlab uses for singular value decompositions, and yet you still decided to waste everyone's time by asking which algorithm Matlab uses for singular value decompositions? Matlab has the best documentation of any software I've ever seen. Ever. Learn how to use it...

    How to accelerate the SVD algorithm?

    As a matter of fact ,I have found the source code of the algorithm. But I wonder the cause of its fast speed.So I hope to find the primitive document about the algorithm. Who may tell me?

    How to accelerate the SVD algorithm?

    You are not friendly,Shoehorn. I have read the MATLAB document. I know it use DGESVD. But I cannot find the details of the algorithm. So I asked the question. Do take any thing for granted. Ok? GUY

    Can you explain the size difference between arrays and pointers in C?

    I tell you my answer. a1,a2,a3 are all arrays. But they are allocated memory in heap not stack.

    Oh, you said nothing.

    How to accelerate the SVD algorithm?

    I've written a program in c language in terms of the GR SVD algorithm. To my dispointment,its performance is worse than the svd of matlab. I wish to get to know which algorithm the MATLAB used. Who may tell me? Thanks.
