List comprehensions vs. functions
显示 更早的评论
Hi, I am new to MATLAB and I am trying to recreate some python code in MATLAB and was wondering if there is anything like this I would be able to do in MATLAB to make life a little easier.
[(-1)**b*0.2*(b+0.1) for b in range(-30,31) if b>5 or b<-5]
Would I be able to do this, or would I need to create a function to do this for me? Thanks for any help in advance.

MATLAB does not have list comprehensions.
List comprehansions are fundamentally just syntatic sugar for loops, so it is not clear how or why you think a function would be necessary. At first glance, some basic indexing applied to matrices would perform the same purpose:

b = -30:30;
b = b(b<-5|b>5);
v = (-1).^b .* 0.2 .* (b+0.1)
Python output:
