[Users-fr] fscanfMat & fprintfMat

[Eric levillain (Gmail)]

BUG: Compared to Scilab 5.3.3, fscanfMat and fprintfMat are very slow 
under Scilab 5.4.0.


Hello,

I performed some tests on Scilab 5.3.3 and Scilab 5.4.0 with this 
following script:


***************************

clc;

clear;

A = ones(1000,1000)+0.1;

tic();

fprintfMat("Matrix.txt", A, "%lg");

s1 = toc();

disp(s1);

fscanfMat("Matrix.txt", "%lg");

s2 = toc();

disp(s2);

***************************

Output on WIN 7 x64:

On Scilab 5.3.3: s1 = 0.748 and s2 = 2.496

On Scilab 5.4.0: s1 = 1.279 and s2 = 39.812 !!!

***************************

Output on LINUX x64

On Scilab 5.3.3: s1 = 0.594 and s2 = 2.422

On Scilab 5.4.0: s1 = 0.658 and s2 = 2.473

***************************

In conclusion, this bug depends on the OS.

Do you know why?

Sincerely yours

Eric
