Linda, If you're familiar with Matlab syntax, you may find this link interesting: http://www.scipy.org/NumPy_for_Matlab_Users
Here another couple of useful links http://www.scipy.org/Tentative_NumPy_Tutorial http://www.scipy.org/Numpy_Functions_by_Category For your specific example, if you want to create a (256,128) array of unsigned integers: import numpy as np a = np.zeros((256,128), dtype=np.uint32) Note that if you intend to fill the array afterwards with other values, it might be more efficient to create an 'empty' array instead of an array full of zeros: b=np.empty((256,128), dtype=uint32) _______________________________________________ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion
