rotationMatrix
rotationMatrix(theta)
rotationMatrix(theta, v)
rotationMatrix(theta, v, format)
Returns a 2-D rotation matrix (2x2) for a given angle (in radians). Returns a 2-D rotation matrix (3x3) of a given angle (in radians) around given axis.
Try it yourself:
| $1 | rotationMatrix(pi / 2)
| |
| $2 | rotationMatrix(unit("45deg"), [0, 0, 1])
| |
| $3 | rotationMatrix(1, matrix([0, 0, 1]), "sparse")
