in interface BivariateGridInterpolator
xval
- All the x-coordinates of the interpolation points, sorted
in increasing order.yval
- All the y-coordinates of the interpolation points, sorted
in increasing order.fval
- The values of the interpolation points on all the grid knots:
fval[i][j] = f(xval[i], yval[j])
.DimensionMismatchException
- if the array lengths are inconsistent.NoDataException
- if any of the arrays has zero length.NonMonotonicSequenceException
- if the array is not sorted.NullArgumentException
