When running some Python experiments — where typically each experiment corresponds to run a simulation under some particular conditions — I find useful to be able to call a particular function from the command line. For example, if I define the functions exp_1, exp_2, and exp_3, I want to be able to ...read more
For some reason finding how to compute the binomial coefficients using Numpy/SciPy is harder than it should (I couldn't find the answer in the first page of a google search).
The answer, though, is quite easy: just use scipy.special.binom. For example:read more
>> import scipy >> print scipy.special ...
In NumPy, masked arrays are quite handy. Say you want to find the index of the smallest positive entry of an array. Doing a[a>0].argmin() doesn't work, because you're removing all the non-positive numbers from a, so you're computing argmin over the wrong array.
Masked ...read more
San Diego, Santa Catalina, San Pedro, where all these names come from? I learned about it reading “The Quark and the Jaguar: Adventures in the Simple and the Complex” by Murray Gell-Man. In 1602 Sebastian Vizcaino was given the mandate to map the coast of California. For each new place ...read more
