[Numpy-discussion] dimension along axis?

in different position so it's inconvenient to identify them. Is there anyway to get dimension along axis? (In this case should be axis0) -- Cheers, Grissiom ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://mail.scipy.org/mailman/listinfo

[Numpy-discussion] linalg.norm along axis?

Hi all, Is there any possibility to calculate norm along axis? For example: a = np.array(( (3,4), (6,8))) And I want to get: array([5.0, 10.0]) I currently use a for loop to achieve this, Is there any more elegant way to do this? -- Cheers, Grissiom

think the testcase is a matter of python loop vs matlab loop rather than python vs matlab. -- Cheers, Grissiom ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
