Hi Andy

you have an example in CVI that takes a Waveform transfore it to a graph and then saving the data in file.

National Instruments\CVI2009\samples\fileio\arrayfile.cws

it will help you understand

There are multiple ways to realize what you want to do.

One simple way is (1) use FileToArray(...) function to read all data into a 1-D arrary and (2) use a standard C loop to parse and rearrange the data into a 2-D array (matrix).

Please post your code so people can understand your problem better and help you.

Some more hints on this:

- FileToArray can directly generate a 2d array if you are starting from an ASCII file (which seems s your case: notepad)

- You need to know the number of rows/columns to dimension the array prior to calling FilToArray

- FileToArray cannot handle files with mixed text/numbers elements: if this is your case you will need to use some low level functions to open the file and scan it

If you can post a sample data file we can be more precise in our suggestions.
