New issue 2222 by [email protected]: Matrix([Matrix, ...]) should check
the row length of empty matrices
http://code.google.com/p/sympy/issues/detail?id=2222
Currently, we have this:
In [20]: Matrix(([1,2,3], Matrix(0,1, lambda i,j:0)))
Out[20]: [1 2 3]
In [21]: Matrix(([1,2,3], Matrix(0, 3, lambda i,j:0)))
Out[21]: [1 2 3]
In [22]: Matrix(([1,2,3], Matrix(0, 4, lambda i,j:0)))
Out[22]: [1 2 3]
To be consistent, only the second version should work. The others should
raise a ShapeError.
