Parameters

trans

Type: Extreme.Mathematics..::..TransposeOperation
A TransposeOperation value that specifies whether the regular or the transposed system should be solved.

n

Type: System..::..Int32
An integer specifying the number of rows and columns of the matrix a. Must be greater than or equal to zero.

nrhs

Type: System..::..Int32
An integer specifying the number of columns in the right-hand side matrix b. Must be greater than or equal to zero.

a

Type: array<System..::..Single>[]()[][]
Double array specifying the n-by-n matrix containing the lower and upper triangular factors as computed by [!:Dgetrf].

aOffset

Type: System..::..Int32
Offset into a of the first element of the matrix.

lda

Type: System..::..Int32
The leading dimension of the array a. Must be greater than or equal to Max(1,m).

ipiv

Type: array<System..::..Int32>[]()[][]
Integer array containing the pivot indexes computed by [!:Dgetrf].

b

Type: array<System..::..Single>[]()[][]
Double array specifying the nrhs-by-n matrix containing the right-hand sides. On exit, this matrix is overwritten with the solution.

bOffset

Type: System..::..Int32
Offset into b of the first element of the matrix.

ldb

Type: System..::..Int32
The leading dimension of the array b. Must be greater than or equal to Max(1,n).

info

Type: System..::..Int32%
Reference to an integer containing a result code. Zero indicates success. Greater than zero indicates U(i,i) is exactly zero. The decomposition has been completed, but the factor U is exactly singular, and division by zero will occur if it is used to solve a system of equations.
