How to loop two vectors in MATLAB?

Question

In python one can use zip to loop multiple vectors or enumerate to get the current index of the looped vector like so

one = [\'A\', \'B         


        

Answer 1

Using printf, or fprintf in Matlab, is pretty good. The Matlab code for your first approach is

one = {'A' 'B' 'C'};
two = [1 2 3];

for ii = 1:length(one)
  fprintf('%s %i\n', one{ii}, two(ii));
end

It's also possible to put the strings into a cell array, without any for loop.

s = cellfun(@(a,b) [a,' ',b], one', ...
    arrayfun(@num2str, two', 'UniformOutput', false),....
    'UniformOutput', false)

Bonus:

>> A = [1;2;3]   
A =
     1
     2
     3
>> A = [1 2 3]   
A =
     1     2     3
>> A = [1,2,3]   
A =
     1     2     3
>> A = [1,2,3;4 5 6;7,8 9]
A =
     1     2     3
     4     5     6
     7     8     9

Bonus 2:

Using i and j is bad. See - Using i and j as variables in Matlab
