Math operators

group NVCV_CPP_CUDATOOLS_MATHOPERATORS

Operators on CUDA compound types resembling the same operator on corresponding regular C type.

This whole group defines a set of arithmetic and bitwise operators defined on CUDA compound types. They work the same way as the corresponding regular C type. For instance, three int3 a, b and c, will accept the operation a += b * c (see example below). Furthermore, the operators accept mixed operands as CUDA compound and regular C types, e.g. two int3 a and b and one int c will accept the operation a += b * c, where the scalar c propagates its value for all components of b in the multiplication and the int3 result in the assignment to a.

using DataType = ...;
DataType pix = ...;
float kernel = ...;
ConvertBaseTypeTo<float, DataType> res = {0};
res += kernel * pix;

tparam T:

Type of the first CUDA compound or regular C type operand.

tparam U:

Type of the second CUDA compound or regular C type operand.

param a:

[in] First operand.

param b:

[in] Second operand.

return:

Return value of applying the operator on a and b.
