LinearSolve[m, b] finds an x which solves the matrix equation m.x == b. LinearSolve[m] generates a LinearSolveFunction[...] which can be applied repeatedly to different b.

Many calculations involve solving systems of linear equations. In many cases, you will find it convenient to write down the equations explicitly, and then solve them using ...

ZeroTest is an option to various linear algebra functions that gives a function to use in testing whether symbolic expressions should be treated as zero.

MessageList[n] is a global object assigned to be a list of the names of messages generated during the processing of the n\[Null]^th input line.

$MessageList is a global variable that gives a list of the names of messages generated during the evaluation of the current input line.

Mathematica incorporates the latest algorithms for solving industrial-scale linear systems, automatically switching between optimal dense and sparse algorithms—and handling ...

LinearSolveFunction[dimensions, data] represents a function for providing solutions to a matrix equation.
