coordsys.lineartransform

Recover the linear transform matrix

Synopsis
lineartransform(type)

Arguments

type	in	Coordinate type
		Allowed:	String from "direction", "stokes", "spectral", "linear", "tabular"

Returns
Vector of double or fail

Description

Recover the linear transform component for the specified coordinate type.

You can set the linear transform with function setlineartransform.

Example

- cs := coordsys(direction=T, linear=3)
- cs.lineartransform('dir')                  # 2 x 2
[[1:2,]
    1 0
    0 1]
- cs.lineartransform('lin')                  # 3 x 3
[[1:3,]
    1 0 0
    0 1 0
    0 0 1]
