structminus
¶ minus
is a function object. Specifically, it is an Adaptable Binary Function. Iff
is an object of classminus<T>
, andx
andy
are objects of classT
, thenf(x,y)
returnsx-y
.The following code snippet demonstrates how to use
minus
to subtract a device_vector offloats
from another.- Template Parameters
T
: is a model of Assignable, and ifx
andy
are objects of typeT
, thenx-y
must be defined and must have a return type that is convertible toT
.
#include <thrust/device_vector.h> #include <thrust/functional.h> #include <thrust/sequence.h> #include <thrust/fill.h> #include <thrust/transform.h> ... const int N = 1000; thrust::device_vector<float> V1(N); thrust::device_vector<float> V2(N); thrust::device_vector<float> V3(N); thrust::sequence(V1.begin(), V1.end(), 1); thrust::fill(V2.begin(), V2.end(), 75); thrust::transform(V1.begin(), V1.end(), V2.begin(), V3.begin(), thrust::minus<float>()); // V3 is now {-74, -75, -76, ..., -925}
