Hi everyone!
Currently I am working using two big data sets. The first one is 6927 kb (already in .mat format) and the second is of size 897 621 KB (in format .csv). The problem is that when I tried to work with them the computer stops working. Does anybody know how to make them less heavy? otherwise (less preferable option) how to slipt it to be able to work with them?
I am working with Matlab R2012 b 64-bit
Thanks a lot for your help!
:)

Use:
M = dlmread(filename,delimiter,[R1 C1 R2 C2])
To access the file in chunks.
