step

Description

Step function.

Signature

/// Requires Capability Set 1:
T step<T>(
    T y,
    T x)
    where T : __BuiltinFloatingPointType;

/// Requires Capability Set 1:
vector<T, N> step<T, int N>(
    vector<T, N> y,
    vector<T, N> x)
    where T : __BuiltinFloatingPointType;

/// Requires Capability Set 1:
matrix<T, N, M> step<T, int N, int M>(
    matrix<T, N, M> y,
    matrix<T, N, M> x)
    where T : __BuiltinFloatingPointType;

/// Requires Capability Set 2:
CoopVec<T, N> step<T, int N>(
    CoopVec<T, N> edge,
    CoopVec<T, N> x)
    where T : __BuiltinFloatingPointType;

Generic Parameters

T: __BuiltinFloatingPointType

N : int

M : int

Parameters

y : T

The threshold value.

x : T

The value to compare against the threshold.

y : vector<T, N>

The threshold value.

x : vector<T, N>

The value to compare against the threshold.

y : matrix<T, N, M>

The threshold value.

x : matrix<T, N, M>

The value to compare against the threshold.

edge : CoopVec<T, N>

x : CoopVec<T, N>

The value to compare against the threshold.

Return value

0 if x is less than y, and 1 otherwise.
