Classification functions¶
xtensor provides the following classification functions for xexpressions and scalars:

::
allclose
(E1 &&e1, E2 &&e2, double rtol = 1e-05, double atol = 1e-08) noexcept¶ Check if all elements in e1 are close to the corresponding elements in e2.
Returns true if all elements in
e1
ande2
are close to each other according to parametersatol
andrtol
.- Return
a boolean
- Parameters
e1
: input array to comparee2
: input arrays to comparertol
: the relative tolerance parameter (default 1e-05)atol
: the absolute tolerance parameter (default 1e-08)
