STPSV solves one of the systems of equations Ax = b or A**Tx = b
[Android.Runtime.Register("STPSV", "(IIILandroid/renderscript/Allocation;Landroid/renderscript/Allocation;I)V", "", ApiSince=23)]
public void STPSV (int Uplo, int TransA, int Diag, Android.Renderscripts.Allocation? Ap, Android.Renderscripts.Allocation? X, int incX);[<Android.Runtime.Register("STPSV", "(IIILandroid/renderscript/Allocation;Landroid/renderscript/Allocation;I)V", "", ApiSince=23)>]
member this.STPSV : int * int * int * Android.Renderscripts.Allocation * Android.Renderscripts.Allocation * int -> unitParameters
- Uplo
- Int32
Specifies whether the matrix is an upper or lower triangular matrix.
- TransA
- Int32
The type of transpose applied to matrix A.
- Diag
- Int32
Specifies whether or not A is unit triangular.
- Ap
- Allocation
The input allocation contains packed matrix A, supported elements type Element#F32.
The input allocation contains vector x, supported elements type Element#F32.
- incX
- Int32
The increment for the elements of vector x, must be larger than zero.
- Attributes
Remarks
STPSV solves one of the systems of equations A*x = b or A**T*x = b

Note: For a N*N matrix, the input Allocation should be a 1D allocation of size dimX = N*(N+1)/2, The following subroutine can is an example showing how to convert a UPPER trianglar matrix 'a' to packed matrix 'b'. k = 0 for i in range(0, n): for j in range(i, n): b[k++] = a[i, j]
