iarray.cosh(iarr: IArray, /)#

Hyperbolic cosine, element-wise.

Equivalent to 1/2 * (ia.exp(x) + ia.exp(-x)).

Parameters

iarr (IArray container) – Input data. Should have a numeric data type.

Returns

out – A lazy expression that must be evaluated via out.eval(), which will compute the actual hyperbolic cosine values.

Return type

iarray.Expr
