I am using the Import Data tool that is available on the Home tab to import csv files - 1200 rows with 35 columns - all numeric with .000 decimals. Matlab imports the file but it is very slow. I'd like to speed it up. Any ideas?

I am importing csv files - using 2012 and 2013 version of Matlab. The files import slowly using the import data tool off the Home tab. Any idea how I can speed it up? My files are single sheet cdv with 1200 rows of ~35 columns - numeric data carried to .000. Thanks!

"single sheet cdv " what's that?

I believe ‘CDV Comma Delimited Value’, likely the same as CSV.

If it's pure numerical data try

    M = dlmread(filename, delimiter)

and

    S = load(filename,'-ascii')

Have you tried readtable()?

t = readtable(fullFileName);

Requires 2013b or later I believe.
