Hi,
I am analyzing data from a 400MB ascii-file. There are about 30 million data points in the file and the execution takes forever.
Currently the program reads and processes the file element-by-element ( val = dlmread(fileName, "emptyvalue", [i, col, i, col]) ) and I suspect that this is a very unafficient way to do it. Could you suggest a better approach?
Regards,
hpon
