Definition

Namespace:
Android.Renderscripts
Assembly:
Mono.Android.dll

DGEMV performs one of the matrix-vector operations y := alphaAx + betay or y := alphaA**Tx + betay

[Android.Runtime.Register("DGEMV", "(IDLandroid/renderscript/Allocation;Landroid/renderscript/Allocation;IDLandroid/renderscript/Allocation;I)V", "", ApiSince=23)]
public void DGEMV (int TransA, double alpha, Android.Renderscripts.Allocation? A, Android.Renderscripts.Allocation? X, int incX, double beta, Android.Renderscripts.Allocation? Y, int incY);
[<Android.Runtime.Register("DGEMV", "(IDLandroid/renderscript/Allocation;Landroid/renderscript/Allocation;IDLandroid/renderscript/Allocation;I)V", "", ApiSince=23)>]
member this.DGEMV : int * double * Android.Renderscripts.Allocation * Android.Renderscripts.Allocation * int * double * Android.Renderscripts.Allocation * int -> unit

Parameters

TransA
Int32

The type of transpose applied to matrix A.

alpha
Double

The scalar alpha.

A
Allocation

The input allocation contains matrix A, supported elements type Element#F64.

X
Allocation

The input allocation contains vector x, supported elements type Element#F64.

incX
Int32

The increment for the elements of vector x, must be larger than zero.
