A method of tensor.

whether two tensors of one rank and shape agree coefficientwise within rtol and atol; MATLAB’s eq, T1 == T2

Syntax

T1.isclose(T2)

Equal up to rounding.

T1.isclose(T2, atol=1e-3)

Every coefficient within 1e-3.

Description

The comparison is that of np.allclose, |a - b| <= atol + rtol |b|, over all coefficients; one answer for the whole list. T1 == T2 is the exact equality, of the frame too.

Input

T1, T2 tensor

Keywords

keyword default description
rtol 1e-08 the tolerance relative to the coefficients of T2
atol 0.0 the absolute tolerance

Output

tf bool
