Function Documentation

cos()

constexpr float ame::cos ( float  x )

inlineconstexpr

cosf.

When CMSIS-DSP is available, use arm_cos_f32() of CMSIS-DSP; when not, use std::cosf()

Parameters

x

phase

Returns

float

sin() [1/2]

constexpr double ame::sin ( double  x )

inlineconstexpr

sin for double.

Parameters

x

radian

Returns

double

Attention

CMSIS-DSP does not support double, so at runtime, std::sin() is always used.

sin() [2/2]

constexpr float ame::sin ( float  x )

inlineconstexpr

sin for float

When CMSIS-DSP is available, use arm_sin_f32() of CMSIS-DSP; when not, use std::sinf()

Parameters

x

radian

Returns

float
