Its also described here nicely
http://distance-ed.math.tamu.edu/Math64 ... node6.html

But it also says that there are methods for accelerating convergence of the QR method.

Could you point to me where it is explained on how to accelerate convergence of QR method?

Dynamic Allocation for 2 dimensional Array

i m doing like this #define MAXROWS 100 float *arr[MAXROWS]; //read no of rows & cols from user for(i=0=i<rows;i++) arr = (float *)malloc(col * sizeof(float)); Here I can have rows at the max MAXROWS. Is it possible to have dynamic allocation of memory without knowing/declaring the maximum no of rows?
