Limit of loading data

[Bill Wang]

Hello Sir,

    I am an octave newbie. I want to load a big data set saved as .csv file. It is really big, about 50K examples. After loading, I checked my variable size, the variable size is smaller the the data set. And I think the data set is not fully loaded. Is there any way to solve it? Or I should import to Access and export? Please give me a relative detailed explanation.

Thanks, 

Bill Wang
