Solves the linear equation op(A)*trsv = x for trsv.

The data types you wire to the A and x inputs determine the polymorphic instance to use.

dtrsv - Solve Linear Eqs (Triangle, single) (DBL)

operation A specifies the operation the VI performs on matrix A, resulting in matrix op(A).

0Direct (default)
1Conjugated & Transposed
2Transposed
A is a real triangular matrix. The VI uses the first N rows and columns in op(A) to solve the linear equations, where N equals the number of elements in x. The number of rows and columns in A must be greater than or equal to N.
x is a real vector.
matrix A type specifies whether A is an upper or lower triangular matrix.

2Lower TriangularA is a lower triangular matrix.
3Upper Triangular (default)—A is an upper triangular matrix.
diagonal specifies the value of the diagonal elements of A.

0Non-unit (default)—The VI uses the original diagonal elements of A.
1Unit—The VI uses a value of 1 for all diagonal elements of A.
dtrsv is a real vector of the same size as x that returns the result of op(A)*dtsrv = x, solved for dtrsv.
error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

ztrsv - Solve Linear Eqs (Triangle, single) (CDB)

operation A specifies the operation the VI performs on matrix A, resulting in matrix op(A).

0Direct (default)
1Conjugated & Transposed
2Transposed
A is a complex triangular matrix. The VI uses the first N rows and columns in op(A) to solve the linear equations, where N equals the number of elements in x. The number of rows and columns in A must be greater than or equal to N.
x is a complex vector.
matrix A type specifies whether A is an upper or lower triangular matrix.

2Lower TriangularA is a lower triangular matrix.
3Upper Triangular (default)—A is an upper triangular matrix.
diagonal specifies the value of the diagonal elements of A.

0Non-unit (default)—The VI uses the original diagonal elements of A.
1Unit—The VI uses a value of 1 for all diagonal elements of A.
dtrsv is a complex vector of the same size as x that returns the result of op(A)*ztsrv = x, solved for ztrsv.
error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.
