I am trying to use if statements to compare two vectors to get a value from a third. I need to display which months of one vector are higher than another then give the months that they are within .2 of each other.

WSFO =[6.7 7.5 8.5 9.5 10.4 10.9 11.2 10.5 9.1 7.6 6.3 6.5];

WOrl =[9.0 9.6 9.9 9.4 8.8 8.0 7.3 7.2 7.7 8.6 8.6 8.5];

Month={'Jan' 'Feb' 'Mar' 'Apr' 'May' 'Jun' 'Jul' 'Aug' 'Sep' 'Oct' 'Dec'};

A = mean(WSFO);

B = mean(WOrl);

fprintf(['\nThe average annual wind speed in San Francisco was (mph)'...

      '\n %f\n'], A);

fprintf(['\nThe average annual wind speed in Orlando was'...

      '(mph)\n %f\n'], B);

C = round(sum(WSFO<A));

D = round(sum(WOrl<B));

fprintf(['\nWind speed is below the annual average in San Francisco' ...

      ' for \n %f months\n'], C);

fprintf(['\nWind speed is below the annual average in Orlando for'...

      '\n %f months\n'], D);

E = sum(WSFO > WOrl);

fprintf(['\nWind speed in San Francisco higher than in Orlando '...

          'during the %d months of\n'], E);

if WSFO > WOrl

      fprintf('%s %s\n',E, Month{1:2:3:4:5:6});

end

F = abs(WSFO - WOrl) <= .2;

if abs(WSFO - WOrl) <= .2

fprintf(['\nWind speed in San Francisco is within ±0.2mph of that in '...

     'Orlando during the %d months of\n'], Apr);

end

I am very new to MATLAB so I apologize in advance for my coding ignorance.

WSFO =[6.7 7.5 8.5 9.5 10.4 10.9 11.2 10.5 9.1 7.6 6.3 6.5];
WOrl =[9.0 9.6 9.9 9.4 8.8 8.0 7.3 7.2 7.7 8.6 8.6 8.5];
Month={'Jan' 'Feb' 'Mar' 'Apr' 'May' 'Jun' 'Jul' 'Aug' 'Sep' 'Oct' 'Dec'};
A = mean(WSFO);
B = mean(WOrl);
fprintf(['\nThe average annual wind speed in San Francisco was (mph)'...
      '\n %f\n'], A);
fprintf(['\nThe average annual wind speed in Orlando was'...
      '(mph)\n %f\n'], B);
C = round(sum(WSFO<A));
D = round(sum(WOrl<B));
fprintf(['\nWind speed is below the annual average in San Francisco' ...
      ' for \n %f months\n'], C);
fprintf(['\nWind speed is below the annual average in Orlando for'...
      '\n %f months\n'], D);

    %%%%%

E = sum(WSFO > WOrl);
fprintf(['\nWind speed in San Francisco higher than in Orlando '...
          'during the %d months of\n'], E);     

idx = WSFO > WOrl ;      
if E ~= 0
      fprintf([repmat('%s,',1,E),'\n'], Month{idx});
end
F = abs(WSFO - WOrl) <= .2;
if abs(WSFO - WOrl) <= .2
fprintf(['\nWind speed in San Francisco is within ±0.2mph of that in '...
     'Orlando during the %d months of\n'], Apr);
end

It's the last two portions I need help with.

   E = sum(WSFO > WOrl);
    fprintf(['\nWind speed in San Francisco higher than in Orlando '...
        'during the %d months of\n'], E);
    if WSFO > WOrl
        fprintf('%s %s\n',E, Month{1:2:3:4:5:6});
    end
    F = abs(WSFO - WOrl) <= .2;
    if abs(WSFO - WOrl) <= .2
        fprintf(['\nWind speed in San Francisco is within ±0.2mph of that in '...
            'Orlando during the %d months of\n'], Apr);
    end

I need to display the months for when the values of WSFO are higher than WOrl and when they are within .2 of each other. I can get the true/false values of when WSFO > WOrl and when they are within .2, but I cannot get the if statement to get work properly with the embedded fprintf.

Edited the answer......I changed one condition, you do the other one.

[Michael Johnson]

That was perfect. Thank you. I got the second part after changing what I needed.
