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

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

Parameters

TransA
Int32

The type of transpose applied to matrix A.

alpha
Single

The scalar alpha.

A
Allocation

The input allocation contains matrix A, supported elements type Element#F32.

X
Allocation

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.

beta
Single

Y
Allocation

The input allocation contains vector y, supported elements type Element#F32.

incY
Int32

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

Remarks

SGEMV performs one of the matrix-vector operations y := alpha*A*x + beta*y or y := alpha*A**T*x + beta*y
