Subject: [Caml-list] laconical input from a file for arrays and/or matrices
Date: Mon, 2 Feb 2004 11:42:18 +0100 [thread overview]
Message-ID: <D15343265276D31197BC00A024A6C110774275@EXS_BDC> (raw)
Hi OCaMLers,
here goes my usual way to input ASCII matrices from file in C++:
// ------- start of fragment -----------
#include <iostream>
#include <vector>
using namespace std;
void input_matrix(vector<vector<double > >&vec) {
int m, n;
cin >> m;
cin >> n;
vec.resize (m);
for( int i = 0; i<m; i++)
vec[i].resize(n);
for( int i = 0; i<m; i++)
for( int j = 0; j<n; j++)
cin >> vec[i][j];
}
// -------- end of fragment -------------
then for matrix :
3
3
1 2 3
4 5 6
7 8 9
stored in ASCII text file mymatrix.dat
i just run my program:
% myprogram < mymatrix.dat
and it is done.
Thus, the few lines of code and i can apply all math I need.
Is there any similar ascetic way in OCaML for
doing the same?
Thanks a priori,
kind regards,
Valery A.Khamenya
