Grids XYZ data using spline interpolation.
SGRID(x, y, z, xi, yi)
x |
- |
A series. The X or horizontal range. |
y |
- |
A series. The Y or vertical range. |
z |
- |
A series. The Z or height data. |
xi |
- |
Optional. A series, the output X range. |
yi |
- |
Optional. A series, the output Y range. |
An array.
(x, y) = fxyvals(-10, 10, 2, -10, 10, 2)
z = cos(x*y)
xyz = sgrid(x[..], y[..], z[..], -10..0.5..10, -10..0.5..10)
Grids the function cos(x*y) over the range -10 to 10 interpolated with an increment of 0.5.
SGRID first interpolates in the direction with the most variability. The output X and Y ranges (xi, yi) are determined from the data if not specified.
