matrix representation doesn't work with order>2 #24

Hi,

the matrix representation seems doesn't work when order larger than 2. For instance, the below code will raise an error: x = np.zeros((10)) d3_dx3 = FinDiff((0, 1, 3)) mat = d3_dx3.matrix(x.shape) print(mat.astype(int))

Sorry for the late reply! All right, there was a bug that should now be fixed. Version 0.8.2 is now available for installation with pip.
