Hello again,
i discovered an error and now I am able to use the 2-dimensional array
zg right.
The problem is still the griddata function. Something is wrong there.
The running program is killed calling the griddata function.
Regards, Paul.
P.S.: My actual Code: (cd is a ContourableData object which extends
Contourable_Data).
pls = new plstream();
pls->init();
PLFLT *x, *y, *z;
PLINT n = cd.count();
x = cd.get_x();
y = cd.get_y();
z = cd.get_value();
const PLINT nn = 20;
PLFLT *xg = new PLFLT[nn];
PLFLT *yg = new PLFLT[nn];
PLFLT **zg;
pls->plAlloc2dGrid(&zg, nn, nn);
double step = 2*28/((double)n-1);
for(int i = 0; i < nn; i++){
double val = -28 + step*(double)i;
xg[i] = val;
yg[i] = val;
}
pls->griddata(x, y, z, n, xg, nn, yg, nn, zg, GRID_DTLI, 0.0);
