LinearSolve¶

Solves the linear system m . x == b.

$ wo 'LinearSolve[{{1, 2}, {3, 4}}, {5, 11}]'
{1, 2}

LinearSolve[m] is an operator: LinearSolve[m][b] equals LinearSolve[m, b].

$ wo 'LinearSolve[{{1, 2}, {3, 4}}][{5, 11}]'
{1, 2}

For a rectangular (non-square) system, a particular solution is returned with the free variables set to 0.

$ wo 'LinearSolve[{{1, 2, 3}, {4, 5, 6}}, {1, 2}]'
{-1/3, 2/3, 0}
