blosc2.arccosh

blosc2.arccosh(ndarr: NDArray | NDField | C2Array | LazyExpr, /) → LazyExpr

Compute the inverse hyperbolic cosine, element-wise.

Parameters:

ndarr (NDArray or NDField or C2Array or LazyExpr) – The input array.

Returns:

out – A lazy expression representing the inverse hyperbolic cosine of the input array. The result can be evaluated.

Return type:

LazyExpr
