cosh

Syntax

cosh(X)

Details

The hyperbolic cosine function.

Note:
The function of DolphinDB's cosh works the same as NumPy's numpy.cosh, except that it only accepts a single parameter, X, and does not support parameters like out or where in numpy.cosh.

Parameters

X is a scalar/vector/matrix.

Returns

A scalar/vector/matrix of type DOUBLE.
