hom2cart

Convert homogeneous coordinates to Cartesian coordinates

Syntax

cart = hom2cart(hom)

Description

cart = hom2cart(hom) converts a set of homogeneous points to Cartesian coordinates.

Examples

Convert Homogeneous Points to 3-D Cartesian Points

h = [0.2785 0.9575 0.1576 0.5; 0.5469 0.9649 0.9706 0.5];
c = hom2cart(h)

c = 2×3

Input Arguments

hom — Homogeneous points

n-by-k matrix

Homogeneous points, specified as an n-by-k matrix, containing n points. k must be greater than or equal to 2.

Example: [0.2785 0.9575 0.1576 0.5; 0.5469 0.9649 0.9706 0.5]

Output Arguments

cart — Cartesian coordinates

n-by-(k–1) matrix

Cartesian coordinates, returned as an n-by-(k–1) matrix, containing n points. Each row of cart represents a point in (k–1)-dimensional space. k must be greater than or equal to 2.

Example: [0.8147 0.1270 0.6324; 0.9058 0.9134 0.0975]
