python - Iterating over Numpy matrix rows to apply a function each? -


i want able iterate on matrix apply function each row. how can numpy matrix ?

use numpy.apply_along_axis(). assuming matrix 2d, can use like:

import numpy np mymatrix = np.matrix([[11,12,13],                       [21,22,23],                       [31,32,33]]) def myfunction( x ):     return sum(x)  print np.apply_along_axis( myfunction, axis=1, arr=mymatrix ) #[36 66 96]

matlab - How to equate a structure array to structure array -

the following code doesn't work, think it's clear want do: my.struct = 1; foo.bar = my.struct; so that foo.bar.struct = 1 basically want fill in my structure array bunch of fields , values. want place struct nested struct within foo.bar while retaining field names. my.struct = 1; foo.bar = my.struct; this places value of my.struct (= 1 ) in foo.bar . of course foo.bar 1 . i think you're after this: my.struct = 1 foo.bar = my;
