TWO OBSCURE ?? First, I have a rather large matrix (type real*8) stored on disk, which I would like to read into memory in a reasonable amount of time << 2 hrs. Preferably in under a minute or so. ReadList doesn't cut it. I was thinking of writing a Mathlink program to pass in the matrix, although I don't know that this would be any faster than ReadList. I know Fortran (90), but Mathlink requires C. The matrix size is about 300 by 200. Secondly, I'm running Windows NT, and I cannot get Todd Gayley's FastBinaryFiles to load. I've checked $Paths to make sure it can find his Binary.exe file. In mathematica I type Install["Binary.exe"] and the kernel just hangs up. Dag Spicer Stanford spicer at leland.stanford.edu
