Description

Get 2-D grid matrices based on the coordinates contained in vectors vX and vY. mX is a matrix where each row is a copy of vX, and mY is a matrix where each column is a copy of vY. Both mX and mY have vX.GetSize() rows and vY.GetSize() columns.

Syntax

BOOL MeshGrid(const vector & vX, const vector & vY, matrix & mX, matrix & mY)

Parameters

vX: [input] Including the coordinates to be repeatedly copied into mX.
vY: [input] Including the coordinates to be repeatedly copied into mY.
mX: [output] Matixbase derived object containing the row-wise copies of vX.
mY: [output] Matixbase derived object containing the column-wise copies of vY.

Return

Return TRUE on successful exit and FALSE on failure.
