Hi Everyone, *) numpy arrays are automatically converted to blitz arrays. That's fine. *) I need to work with blitz Matrix objects, but I noticed that numpy matrix objects are not converted to them and I get a compilation error too 3) Does someone on the list succeeded doing that? Or is there a workaround to create quickly a blitz matrix object from a numpy 2D array or numpymatrix without wasting time in casting operations? It would be nice having an automatic translation of numpy.matrix to blitz Matrix as matrices are used frequently in scientific computing. Any suggestion or help would be very glad. Paolo # EXAMPLE CODE  import numpy import scipy #Dot product with arrays (it works) x=numpy.array([[1,2,],[3,4]]) y=numpy.zeros((2,2)) scipy.weave.inline("""y=x*x;""",['x','y'],type_converters=weave.converters.blitz,compiler='gcc',force=1) #Matrix multiplication with matrix (gives compilation error) X=numpy.matlib.mat('1 2; 3 4') Y=numpy.matlib.zeros((2,2)) scipy.weave.inline("""Y=X*X;""",['X','Y'],type_converters=weave.converters.blitz,compiler='gcc') #
