Hi, All
Is there a way to use multiple variables in pure function with map.
What I want to do is like this:
ab = {{1, 2}, {2, 3}, {3, 4}};
(#[[1]] + #[[2]]) & /@ ab
{3, 5, 7}
Instead of refer to elements in list I want to use multiple variables
in pure function.
something like this:
ab = {{1, 2}, {2, 3}, {3, 4}};
(#1 + #2) & /@ ab
To do the same thing as the above example.
Best
