min_max

min_max#

Entry point to compute min and max values.

Description and Assumptions

The oneapi::math::stats::min_max function is used to compute min and max arrays (min and max values for each dataset’s dimension).

min_max supports the following precisions for data:

T

float

double

min_max (buffer version)#

Syntax

namespace oneapi::math::stats {
template<method Method = method::fast, typename Type, layout ObservationsLayout>
    void min_max(sycl::queue& queue,
    const dataset<ObservationsLayout, sycl::buffer<Type, 1>>& data,
    sycl::buffer<Type, 1> min,
    sycl::buffer<Type, 1> max);
}

Template Parameters

Method

Method which is used for estimate computation. The specific values are as follows:

  • oneapi::math::stats::method::fast

Type

Data precision.

ObservationsLayout

Data layout. The specific values are described in dataset.

Input Parameters

queue

The queue where the routine should be executed.

data

Dataset which is used for computation.

Output Parameters

min

sycl::buffer array of min values.

max

sycl::buffer array of max values.

Throws

oneapi::math::invalid_argument

Exception is thrown when min.get_count() == 0, or max.get_count() == 0, or dataset object is invalid

min_max (USM version)#

Syntax

namespace oneapi::math::stats {
template<method Method = method::fast, typename Type, layout ObservationsLayout>
    sycl::event min_max(sycl::queue& queue,
    const dataset<ObservationsLayout, Type*>& data,
    Type* min,
    Type* max,
    const std::vector<sycl::event> &dependencies = {});
}

Template Parameters

Method

Method which is used for estimate computation. The specific values are as follows:

  • oneapi::math::stats::method::fast

Type

Data precision.

ObservationsLayout

Data layout. The specific values are described in dataset.

Input Parameters

queue

The queue where the routine should be executed.

data

Dataset which is used for computation.

dependencies

Optional parameter. List of events to wait for before starting computation, if any.

Output Parameters

min

Pointer to the array of min values.

max

Pointer to the array of max values.

Throws

oneapi::math::invalid_argument

Exception is thrown when min == nullptr, or max == nullptr, or dataset object is invalid

Return Value

Output event to wait on to ensure computation is complete.
