template<enum Backend, class Operand, class ReturnType, class UnaryOp>
struct shogun::linalg::implementation::elementwise_unary_operation< Backend, Operand, ReturnType, UnaryOp >
Template struct elementwise_unary_operation. This struct is specialized for computing element-wise operations for both matrices and vectors of CPU (SGMatrix/SGVector) or GPU (CGPUMatrix/CGPUVector).
