Details:

This is unexpected behavior, to return false for a symmetric matrix simply
because it is char. Symmetry as a property is not restricted to numeric types.
Is this being done with the aim of Matlab compatibility?


octave:1> A = ["evil"; "vile"; "ills"; "lest"]
A =

evil
vile
ills
lest

octave:2> A == A'
ans =

  1  1  1  1
  1  1  1  1
  1  1  1  1
  1  1  1  1

octave:3> issymmetric (A)
ans = 0
