Comment #6 on issue 959 by pr...@goodok.ru: make sympy do vector
manipulations
http://code.google.com/p/sympy/issues/detail?id=959
Thanks for reminding about lambda. With the am of it one can speed up
computations indeed. Can I ask here a question.
In current implementation there is a `map` used in matrices (with
constructor to do not break inmutability):
def applyfunc(self)
Matrix(self.rows,self.cols,map(f,self.mat))
So, is it worth to change `map` to `lambda` or not?
And also, is there another deep problems exists with `applyfunc`?
