GRID Function

Standard Library function that generates a uniform grid from irregularly-spaced data.

Usage

result = GRID(xtmp, ytmp, ztmp)

Input Parameters

xtmp—The vector containing the x-coordinates of the irregularly-spaced input data.

ytmp—The vector containing the y-coordinates of the irregularly-spaced input data.

ztmp—The vector containing the z-coordinates of the irregularly-spaced input data.

Returned Value

result—Array containing gridded z values applied to a uniform XY grid.

Keywords

Nghbr—The number of neighboring data points to be used in the gridding algorithm. Must be in the range of {3 ... 25}. (Default: 3)

Nx—The number of columns in the resulting array. Must be ≤ 200.

Ny—The number of rows in the resulting array. Must be ≤ 200.

Discussion

As of PV‑WAVE version 6.0, the previously used GRID procedure algorithm has been discontinued. GRID now calls the FAST_GRID3 procedure directly. If you prefer to use the previously supported GRID algorithm, please contact Rogue Wave’s Technical Support.

note

PV‑WAVE GTGRID is an optional software package for advanced gridding. It gives you additional interpolation and extrapolation power by providing access to a library of gridding routines provided by Geophysical Techniques, Inc.
