To all,
I came across an old thread in the archives in which Alexander Schmolck gave
an example of a Matlab like matrix formatter he authored for Python. Is this
formatter still available some where? Or has anyone else done anything
similar?

P.S. Here is a short example of the output:


>>>* a
*array([[-9.90000000e+01,  -9.72817182e+01,   0.00000000e+00,  -7.99144631e+01],
       [-4.54018500e+01,   4.84131591e+01,   3.03428793e+02,   9.96633158e+02],
       [2.88095799e+03,   8.00308393e+03,   2.19264658e+04,   5.97741417e+04]])
>>>* m = matrix(a)
*>>>* m
*matrix('''
1.0E+04 *

  -0.00990   -0.00973    0.00000   -0.00799

   0.28810    0.80031    2.19265    5.97741
''')
>>>* m.show('long')
*matrix('''
1.0E+04 *
