fspline2

fspline2 executes a 2-dimensional “matrix to matrix” interpolation.

rmZi = fspline2(rvX, rvY, rmZ, rvXi, rvYi, rsSmoothFactor)

Return Value

rmZi is the interpolated matrix for the given rvXi and rvYi coordinates.

Parameters

rvX

rvX is a vector with x-coordinates for the matrix rmZ.

rvY

rvY is a vector with y-coordinates for the matrix rmZ.

rmZ

rmZ is a matrix.

rvXi

rvX is a vector with x-coordinates for the new matrix rmZi.

rvYi

rvY is a vector with y-coordinates for the new matrix rmZi.

rsSmoothFactor

rsSmoothFactor is a number equal or greater than 0.0. No smoothing is performed for 0.0.

Example

def test_fspline2()
{
    if (version(1) < 5200) return;
    m = [0, 0, 0;
         0, 1, 0;
         0, 0, 0];
    x = [0, 0.5, 1]
    y = x;
    mi = fspline2(x, y, m, xi = linspace(0, 1, 50), xi, 1);
    hData = plotxyz(xi, xi, mi);

    if (_g().unit_test_cleanup) {
        hLayer = GetParent(hData);
        hPage =  GetParent(hLayer);
        hDoc =  GetParent(hPage);
        DocDestroy(hDoc);
    }
}
test_fspline2();
