Re: gsl win version

I think you can install gsl on windows thru cygwin. http://cygwin.com/cgi-bin2/package-cat.cgi?file=gsl%2Fgsl-1.7-1&grep=gsl <http://cygwin.com/cgi-bin2/package-cat.cgi?file=gsl%2Fgsl-1.7-1&grep=gsl> > > On 1/25/06, Yun Li <liyunhy@xxxxxxxxx> wrote: > > > > Hi, > > > > I new in the list.

Re: Maximum size of matrices

Well. Assuming ur datatypes are "floats" then 128 bits per float (right?), with 16000*3000 floats means abt 1 GIG of RAM + ull need space in RAM for temporary work areas for the diagonalization process that's typically goes as N^2 or some such power law, so waaay too much I think (my numerical analysis fundas are somewhat sketchy, but I think if ur diagonalizing matrices using Householder-type Transformations+Jacobi rotations then space requirements go as some power law of the matrix order) But I think that most distributive teragrids can take the load (if that's where ur doing it). If ur using "doubles" then out of the question in standard boxen.
