Converting large .mat files

Post by vpconway » Thu Jun 04, 2015 8:04 pm

I am attempting to convert a 100MS digital capture (6 signals) to a text file to be used as test bench data. I've seen other posts about the 1MS limit for text an csv files so, as recommended, I've saved the waveform in .mat format.

Unfortunately I can't pull this much data into matlab. The .mat structure is array oriented making it a little more difficult to convert a line at a time. Can anyone point me point me to a decent starting point? What I've found so far requires reading all the data into memory.

Thanks.

You might want to look at memory mapping using either memmapfile or matfile.
