Generate a Mesh Grid

Generate two matrices for use in three-dimensional plots.

meshgrid(x, y = x)

Arguments

x

numerical vector, represents points along the x-axis.

y

numerical vector, represents points along the y-axis.

Details

The rows of the output array X are copies of the vector x; columns of the output array Y are copies of the vector y.

Value

Returns two matrices as a list with X and Y components.

Note

The three-dimensional variant meshgrid(x, y, z) is not yet implemented.
