Solves either op(A)*trsm = alpha*x or trsm*op(A) = alpha*x for trsm.

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

Use the pull-down menu to select an instance of this VI.

dtrsm - Solve Linear Eqs (Triangle, multiple) (DBL)

side specifies the position of A in the linear equations.

0Right—The VI solves the linear equations op(A)*dtrsm = alpha*X.
1Left (default)—The VI solves the linear equations tsrm*op(A)*dtrsm = alpha*X.
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 K rows and columns in op(A) to solve the linear equations. If you set side to Left, K equals the number of rows in x. If you set side to Right, K equals the number of columns in x. The number of rows and columns in A must be greater than or equal to K.
x is a real matrix.
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.
dtrsm is a real matrix of the same size as x that returns the results of of op(A)*dtsrm = alpha*x or dtsrm*op(A) = alpha*x solved for dtrsm.
alpha is the real scale factor for x. The default is 1.
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.

ztrsm - Solve Linear Eqs (Triangle, multiple) (CDB)

side specifies the position of A in the linear equations. The default is Left.

0Right—The VI solves the linear equations op(A)*ztrsm = alpha*X.
1Left (default)—The VI solves the linear equations tsrm*op(A)*ztrsm = alpha*X.
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 K rows and columns in op(A) to solve the linear equations. If you set side to Left, K equals the number of rows in x. If you set side to Right, K equals the number of columns in x. The number of rows and columns in A must be greater than or equal to K.
x is a complex matrix.
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.
ztrsm is a real matrix of the same size as x that returns the results of of op(A)*ztsrm = alpha*x or ztsrm*op(A) = alpha*x solved for ztrsm.
alpha is the real scale factor for x. The default is 1.
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.
