I want to raise a 2-dimensional numpy array, let\'s call it A, to the power of some number n, but I have thus far failed to find the function or operator to do that.
I have the following call to numpy.linalg.lstsq: http://docs.scipy.org/doc/numpy/reference/generated开发者_开发百科/numpy.linalg.lstsq.html
At the heart of an application (written in Python and using NumPy) I need to rotate a 4th order tensor. Actually, I need to rotate a lot of tensors many times and this is my bottleneck. My naive imple
I am using the distribution classes in scipy.stats.distributions and need to serialize instances for storage and transfer. These are quite complex objects, and they don\'t pickle. I am trying to devel
I am implementing some satellite image filters, starting with one known as the Enhanced Lee filter. The images are easily up to 5000x5000 pixels and more. My current implementation is running out of m
I do a lot of statistical work and use Python as my main language. Some of the data sets I work with though can take 20GB of memory, which开发者_Go百科 makes operating on them using in-memory function
This must be a really basic question: I am trying to use Matplotlib. Here\'s the basic example from the documentation.
I\"m trying to install numpy and scipy for a data analysis class I have this semester. I\'m trying to install it from the package on sourceforge.net, but as I follow the wizard I can\'t select my HD.
I\'m making graphs using scipy on python 2.7 on Windows 7 64 bit.I installed it from http://www.lfd.uci.edu/~gohlke/pythonlibs/.
Suppose I have a NxN matrix M (lil_matrix or csr_matrix) 开发者_StackOverflow社区from scipy.sparse, and I want to make it (N+1)xN where M_modified[i,j] = M[i,j] for 0 <= i < N (and all j) and M[
