Trigonometric functions

xtensor provides the following trigonometric functions for xexpressions and scalars:

Defined in xtensor/xmath.hpp

template <class E>
auto xt::sin(E &&e)

Sine function.

Returns an xfunction for the element-wise sine of e (measured in radians).

Return
an xfunction
Parameters

template <class E>
auto xt::cos(E &&e)

Cosine function.

Returns an xfunction for the element-wise cosine of e (measured in radians).

Return
an xfunction
Parameters

template <class E>
auto xt::tan(E &&e)

Tangent function.

Returns an xfunction for the element-wise tangent of e (measured in radians).

Return
an xfunction
Parameters

template <class E>
auto xt::asin(E &&e)

Arcsine function.

Returns an xfunction for the element-wise arcsine of e.

Return
an xfunction
Parameters

template <class E>
auto xt::acos(E &&e)

Arccosine function.

Returns an xfunction for the element-wise arccosine of e.

Return
an xfunction
Parameters

template <class E>
auto xt::atan(E &&e)

Arctangent function.

Returns an xfunction for the element-wise arctangent of e.

Return
an xfunction
Parameters

template <class E1, class E2>
auto xt::atan2(E1 &&e1, E2 &&e2)

Artangent function, using signs to determine quadrants.

Returns an xfunction for the element-wise arctangent of e1 / e2, using the signs of arguments to determine the correct quadrant.

Return
an xfunction
Note
e1 and e2 can’t be both scalars.
