vrrotvec2mat
Convert rotation from axis-angle to matrix representation
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 vectorr
, with the default algorithm parameters replaced by values defined inoptions
.
Theoptions
structure contains the parameterepsilon
that represents the value below which a number will be treated as zero (default value is 1e-12).
The rotation vector,r
, is a row vector of four elements, where the first three elements specify the rotation axis, and the last element defines the angle.
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.
