In linear algebra a rotation matrix is a transformation matrix that is used to perform a rotation in Euclidean spaceFor example using the convention below the matrix rotates points in the xy plane counterclockwise through an angle θ with respect to the positive x axis about the origin of a two-dimensional Cartesian coordinate system. Five fundamental matrix decompositions which consist of pairs or triples of matrices permutation vectors and the like produce results in five decomposition classes. The calculator will show a step-by-step explanation.
Let A be a square n by n matrix over a field K eg the field R of real numbers. These decompositions are accessed by the Matrix class to compute solutions of simultaneous linear equations determinants inverses and other matrix functions. Transpose is just a flipped form of the original matrix and can be achieved by simply switching the rows with.
