Purpose
-------
The purpose of this module is to read and write
Comma Separated Values (CSV) data files.
The goal of this toolbox is to improve the flexibility, consistency and speed of
CSV reading and writing with respect to Scilab built-in
write_csv and read_csv functions.
On some large data files, we observed a 100x improvement of the
speed.
Features
--------
* csv_default : Get or set defaults for csv files.
* csv_getToolboxPath : Returns the path to the current module.
* csv_read : Read comma-separated value file
* csv_stringtodouble : Convert a matrix of strings to a matrix of doubles.
* csv_textscan : Read comma-separated value in a matrix of strings
* csv_write : Write comma-separated value file
To compare speed:
with optimized functions:
stacksize('max');
M = ones(1000, 1000);
tic();
csv_write(M, TMPDIR + "/csv_write_1.csv");
toc()
tic();
r = csv_read(TMPDIR + "/csv_write_1.csv")
toc()
with default scilab functions (be patient):
stacksize('max');
M = ones(1000, 1000);
tic();
write_csv(M, TMPDIR + "/csv_write_1.csv");
toc()
tic();
r = read_csv(TMPDIR + "/csv_write_1.csv")
toc()
