My issue is about the behavior of linalg.inv for arrays of shape (0, 0). I would like to move from numpy.linalg to scipy.linalg, but with scipy inverting this kind of matrices is not possible. Normally my functions runs with (M, M) matri...
Next, the demo program solves the system of equations directly, using the NumPy solve function: XMLCopy x = spla.solve(A, b) print "Using x = linalg.solve(A,b) gives x = " print x Many SciPy and NumPy functions have optional parameters with default values, which is somewhat equivalent...
