ScriptIntrinsicBLAS.DSYR2 Method

Definition

Namespace:

Android.Renderscripts

Assembly:

Mono.Android.dll

DSYR2 performs the symmetric rank 2 operation A := alphaxyT + alphayxT + A

[Android.Runtime.Register("DSYR2", "(IDLandroid/renderscript/Allocation;ILandroid/renderscript/Allocation;ILandroid/renderscript/Allocation;)V", "", ApiSince=23)]
public void DSYR2 (int Uplo, double alpha, Android.Renderscripts.Allocation? X, int incX, Android.Renderscripts.Allocation? Y, int incY, Android.Renderscripts.Allocation? A);

[<Android.Runtime.Register("DSYR2", "(IDLandroid/renderscript/Allocation;ILandroid/renderscript/Allocation;ILandroid/renderscript/Allocation;)V", "", ApiSince=23)>]
member this.DSYR2 : int * double * Android.Renderscripts.Allocation * int * Android.Renderscripts.Allocation * int * Android.Renderscripts.Allocation -> unit
