Hi
I am trying to import data from csv file with size (1046520 1). Using the importdata function. K = importdata('caamel.csv'); It is taking over an hour to compute my program. What is the fastest way make computation easier when importing very large files
Your help will be highly appreciated
Regards

textscan() would probably be faster.

Hi,
There are several builtin options/functions in MATLAB to get the data imported faster than import wizard or importdata(). They are csvread('caamel.csv'), dlmread('caamel.csv') and ...fscanf(), textscan(). Moreover, if all of your data are numerical and only comma is used as separtor, then you can use load('caamel.csv') command, as well which is much faster than importdata.
Good luck.
