In Linear Algebra, the Doolittle Matrix Decomposition is an LU decomposition which decomposes a matrix into a Lower Triangular Matrix (L) and an Upper Triangular Matrix (U).

The Doolittle LU Decomposition iPad app enables the entry of 2x2, 3x3 and 4x4 matrices, checks for matrix entry validity and calculates and displays the resulting Lower Triangular Matrix and Upper Triangular Matrix.

The Doolittle LU Decomposition iPhone app enables the entry of 2x2 and 3x3 matrices, checks for matrix entry validity and calculates and displays the resulting Lower Triangular Matrix and Upper Triangular Matrix.
