Solves a linear system AX = Y.  ## input matrix

A square or rectangular matrix.

The number of rows in input matrix must equal the number of elements in the known vector. Otherwise, the node returns an empty array for solution vector and returns an error.

If this input is singular and the matrix type is General, the node finds the least-square solution. Otherwise, this node returns an error when this input is singular. ## known vector

An array of known, dependent-variable values.

The number of rows in input matrix must equal the number of elements in the known vector. Otherwise, the node returns an empty array for solution vector and returns an error. ## matrix type

The type of matrix represented by input matrix. Specifying the type of input matrix can allow this node to execute more quickly by avoiding unnecessary computations, which could introduce numerical inaccuracy.

 General input matrix is a matrix that you cannot describe with one of the other categories. Positive definite input matrix is positive-definite. Lower triangular input matrix is lower triangular. Upper triangular input matrix is upper triangular.

Default: General ## solution vector

The solution X to AX = Y where A is the input matrix input and Y is the known vector input. ## error

A value that represents any error or warning that occurs when this node executes.
