Hi!
Why standalone octave program runs too slowly (more than 20 seconds for simple program)?
How i can improve performance?
Octave version: 4.0.0
Platform: Windows 7 (x64)
Machine: Core-i7, RAM 16Gb, 124 Gb SSD
Here is my standalone.cc file (taken from
http://www.gnu.org/software/octave/doc/interpreter/Standalone-Programs.html#Standalone-Programs):
#include <iostream>
#include <octave/oct.h>
int
main (void)
{
std::cout << "Hello Octave world!\n";
int n = 2;
Matrix a_matrix = Matrix (n, n);
for (octave_idx_type i = 0; i < n; i++)
for (octave_idx_type j = 0; j < n; j++)
a_matrix(i,j) = (i + 1) * 10 + (j + 1);
std::cout << a_matrix;
return 0;
}
$ mkoctfile -I/c/ProgramData/Octave-4.0.0/include/octave-4.0.0/ -I/c/ProgramData/Octave-4.0.0/include/octave-4.0.0/octave/ -L/C/ProgramData/Octave-4.0.0/lib/ -L/C/ProgramData/Octave-4.0.0/lib/octave/4.0.0/ --link-stand-alone standalone.cc
-o standalone
$ time ./standalone.exe
Hello Octave world!
