Rotation matrices change the orientation of a vector or object without changing its length, angles, or shape. A rotation about one coordinate axis leaves that axis unchanged while mixing the other two coordinates through sine and cosine. Every proper rotation matrix is orthogonal, satisfying R^{T}R=I, with determinant +1. Its inverse is therefore its transpose. Rotations about several axes are combined through matrix multiplication, but their order matters because three-dimensional rotations generally do not commute. These matrices are used to orient cameras in computer graphics, control robotic arms, track spacecraft attitude, transform coordinate systems, and estimate the pose of objects in computer vision.
Transpose and inverse matrices explained step by step. The transpose changes rows into columns, while the inverse reverses the effect of a matrix when it exists.

A coefficient matrix can only have an inverse if the system of equations it represents has a unique solution. If the determinant of the matrix is zero, then it will not have an inverse; the matrix is then said to be singular. Only non-singular matrices have inverses.
