ImageDeconvolve[image, ker] gives a deconvolution of image using kernel ker.

Mathematica has the world's largest collection of consistent multifont mathematical notation characters—all fully integrated into both typesetting and symbolic expression ...

Matrix inversion. Here is a simple 2×2 matrix. This gives the inverse of m. In producing this formula, Mathematica implicitly assumes that the determinant ad-bc is nonzero.

RotationMatrix[\[Theta]] gives the 2D rotation matrix that rotates 2D vectors counterclockwise by \[Theta] radians.RotationMatrix[\[Theta], w] gives the 3D rotation matrix ...
