I'd like to import data from a file. The file is a standard ASCII text
file which contains a matrix of numbers. Matrix columns are "tab"
separated, matrix rows are "EOL" seperated. Numbers use coma "," as a
decimal point specifier.
So the file looks like this:
1,234 1,567 1,89
2,234 2,567 2,89
3,234 3,567 3,89
I know how to do this using Import:
Import["MyFile.txt", "Table",
ConversionOptions -> {NumberPoint -> ","}] ;
However, Import is not the function I'd like to use, because it is realy
slow over large files.
I wonder if someone knows a way to use something faster than Import (I
namely think of ReadList) with coma-numbers?
