public struct clVector
Open CL vector class with overloaded operators.
Declare clVector to run computation on Open CL Be carefull to declare clVector only for local variables with short lifetime. Call the Create method for clVector, if the variable is a global variable or a variable with a longer life.If the Create method (constuctor) is called, the clVector creates its own memory object in GPU memory, otherwise object cache is used.
Examples
csharp
clVector b;
clVector c;
TSingleArray bv;
b = clVector(TDoubleArray.Create(1,1,1,1)); b = new double[] {1,1,1,1};
b.Scale(2);
c = b*2 + Cplx(2,3); c = b*2 + 2 + 3i
b.Add(c);
b.CopyToArray(bv); //copy data back to host from GPUProperties
