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.
