In python, given one matrix of size 3*2 like A=[[x11,x12,x13],[x21,x22,x23]] and a column vector b=[mu1;mu2]. If I want to compute the Euclidean distance between each column of A and vector b. For example, for the first column, the distance ‘d1` is given by A=[[x11,x12,x13],[x21,x22,x23]] b=[[mu1],[mu2]] d1=(x11-mu1)^2+(x21-mu2)^2 #second column d2=(x12-mu1)^2+(x22-mu2)^2 # so on So the distance ..

I am trying to understand the implementation of numpy by debugging its source code. I run the python code import numpy; numpy.add(1, 1) then use GDB to backtrace from its C implementation function LONG_add_avx2. To my surprise, I don’t see the numpy.add appeared in the backtrace call stack. Instead, python is calling numpy.ufunc , not ..
