please tell me can sum as in Emgu.CV.GPU.GpuMat ?

This example does not work me :

GpuMat<int> a = 3;
GpuMat<int> b = 7;

GpuMat<int> sum = new GpuMat<int>(a.Size);
GpuInvoke.Add(a, b, sum, null, null);

Please can you tell me how it's done?

Thanks for your attention

need to convert a for loop C# to for loop Emgu.CV.GPU C#

I need to accelerate the processing speed of an image

and the for loop, I run mathematical calculations of multiplication, addition and division

I need to run it on Emgu.CV.UI.ImageBox

I have a list of data X and Y but I have to tell the system how many groups exist according to the distance of the items of group Y.

X....Y
