    _______________________________________________________

Details:

isnumeric() should report true only for objects which are integer, real, or
complex arrays; logical and character arrays are excluded.  The function works
correctly on full matrices but not on sparse ones.


octave:4> a = true(2)
a =

   1   1
   1   1

octave:5> isnumeric (a)
ans = 0
octave:6> b = sparse (a)
b =

Compressed Column Sparse (rows = 2, cols = 2, nnz = 4 [1e+02%])

  (1, 1) ->  1
  (2, 1) ->  1
  (1, 2) ->  1
  (2, 2) ->  1

octave:7> typeinfo (b)
ans = sparse bool matrix
octave:8> isnumeric (b)
ans =  1
