[Scilab-users] Scilab 6.1 too slow to list large vectors

[Federico Miyara]

Stéphane,

I simplified and diversified the test:

tic
u = rand(100,1000)
toc

takes
16 s in 6.1
10 s in 6.0.2

tic
u = u(:)'
toc

takes
66 s in 6.1
1.29 s in 6.0.2

tic
u = u(:)
toc

takes
107 s in 6.1
1.52 s in 6.0.2

tic
u = matrix(u,1000,100)
toc

takes
16 s in 6.1
10 s in 6.0.2

tic
u = matrix(u,100, 100, 10)
toc

takes
0.5 s in 6.1
0.5 s in 6.0.2

Seems as if vertical (many line feeds) print took more time than 
horizontal print.

Regards,

Federico Miyara
