I have a bunch of csv datasets, about 10Gb in size开发者_JS百科 each. I\'d like to generate histograms from their columns. But it seems like the only way to do this in numpy is to first load the entir
I am trying to export a list of text strings from Python to MATLAB using scipy.io. I would like to use scipy.io because my desired .mat file should include both numerical matrices (which I le开发者_如
I have tuple of lists. One of these lists is a list of scores. I want to convert the list of scores to a numpy array to tak开发者_开发问答e advantage of the pre-built stats that scipy provides.
In Numpy, ix_() is used to grab rows and columns of a matrix, but it doesn\'t seem to work with sparse matrices. For instance, this code works because it uses a dense matrix:
I\'m trying to convert the following code to Python from MATLAB for an EEG Project (partly because Python\'s slightly cheaper!)
If I am using the sparse.lil_matrix format, how can I remove a column from t开发者_如何学编程he matrix easily and efficiently?Much simpler and faster. You might not even need the conversion to csr, bu
I am trying to integrate a multivariable function in SciPy over a 2D area. What would be the equivalent of the following Mathematica code?
has anyone used unladen-swallow with numpy/scipy for numeric/scientific applications?Is it significantly faster in y开发者_StackOverflow中文版our experience?Any opinions would be great.Nobody has exte
I have an irregular mesh which is described by two variables - a faces array that stores the indices of the vertices that constitute each face, and a verts array that stores the coordinates of each ve
Is there any advantage to using numpy when you\'re doing a large 开发者_运维技巧number of operations on lists of binary values?How about integers within a small range (like just the numbers 1,2, and 3
