rspline2

rspline2 executes a 2-dimensional “matrix to matrix” interpolation.

rmZi = rspline2(rvX, rvY, rmZ, rvXi, rvYi)

rmZi = rspline2(rvX, rvY, rmZ, rvXi, rvYi, rsTensionFactor)

Return Value

rmZi is the interpolated matrix for the rvXi, 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

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

rvYi

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

rsTensionFactor

rsTensionFactor is a number in the range 0 to 100. For 0 a cubic spline is calculated. For high values (up to 100) a polygon is calculated. Default value is 1.

def test_rspline2()
{
    if (version(1) < 5200) return;

    m = [0, 0, 0;
         0, 1, 0;
         0, 0, 0];
    x = [0, 0.5, 1]
    y = x;
    mi = rspline2(x, y, m, xi = linspace(0, 1, 50), xi);
    plotxyz(xi, xi, mi);
}
