Checks whether a tensor is symmetric with respect to one or more groups of
modes.
Usage
issymmetric(x, grps = NULL, ...)
# S3 method for class 'Tensor'
issymmetric(x, grps = NULL, tol = 0, ...)
Arguments
- x
A Tensor object.
- grps
A vector of modes or list of mode vectors.
- ...
Additional arguments passed to methods.
- tol
Nonnegative tolerance for approximate symmetry (0, the
default, requires exact equality and uses the compiled kernel).
