vrrotvec2mat

(To be removed) Convert rotation from axis-angle to matrix representation

collapse all in page

vrrotvec2mat will be removed in a future release. For more information, see Version History.

Syntax

m = vrrotvec2mat(r)
m = vrrotvec2mat(r,options)

Description

m = vrrotvec2mat(r) returns a matrix representation of the rotation defined by the axis-angle rotation vector, r.

m = vrrotvec2mat(r,options) returns a matrix representation of rotation defined by the axis-angle rotation vector r, with the default algorithm parameters replaced by values defined in options.

To rotate a column vector of three elements, multiply it by the rotation matrix. To rotate a row vector of three elements, multiply it by the transposed rotation matrix.

Input Arguments

collapse all

Rotation vector, r, specified as a row vector of four elements, where the first three elements specify the rotation axis, and the last element defines the angle.

The options structure, containing the parameter epsilon that represents the value below which a number will be treated as zero (default value is 1e-12).

Output Arguments

Matrix representation of rotation defined by the axis-angle rotation vector r, with the default algorithm parameters replaced by values defined in options

R2023b: To be removed

The vrrotvec2mat will be removed in a future release. Instead, use sim3d classes and Simulation 3D blocks to interface MATLAB® and Simulink® with the Unreal Engine® 3D simulation environment. To get started, see Create 3D Simulations in Unreal Engine Environment.
