ILMathmeshgrid Method (InArraySingle, InArraySingle, OutArraySingle)

public static RetArray<float> meshgrid(
	InArray<float> X,
	InArray<float> Y,
	OutArray<float> outY = null
)

Public Shared Function meshgrid ( 
	X As InArray(Of Single),
	Y As InArray(Of Single),
	Optional outY As OutArray(Of Single) = Nothing
) As RetArray(Of Single)

Dim X As InArray(Of Single)
Dim Y As InArray(Of Single)
Dim outY As OutArray(Of Single)
Dim returnValue As RetArray(Of Single)

returnValue = ILMath.meshgrid(X, Y, 
	outY)

Parameters

X

Type: ILNumericsInArraySingle
Vector of x values.

Y

Type: ILNumericsInArraySingle
Vector of y values.

outY (Optional)

Type: ILNumericsOutArraySingle
[Output, Optional]: if on entry outY is not null it holds the values for the Y dimension on return.

Return Value

The matrices returned can conveniently be used to evaluate and visualize functions of 2 variables over a grid of (X Y) positions.

Note that the X dimension goes along the rows, while the second dimension is considered the columns! This deviates from the common intuition and the actual storage order of matrix elements (i.e.: first dimension along the columns and 2nd dimension along the rows). The reason for it is the convenience this order gives for plotting purposes: In most plots the X axis is expected to run horizontaly.
