How come this codes works, but the other one doesn't.

(WORKS) %% variables

V = [17.43 11.46 8.11 4.23 2.29 30.18 19.84 14.05 7.34 3.96 34.85 22.91 16.22 8.47 4.57 13.18 19.84 14.05 7.34 3.96 17.43 11.46 8.11 4.23 2.29];

val = input('Choose a distance between 0 and 36 feet \n');

tmp = abs(V-val);

[xp xp] = min(tmp);

C = V(xp);

%% conditional

if xp <= 25 && xp >=21;

    A = 75;

elseif xp <= 20 && xp >=16;

    A = 60;

elseif xp <= 15 && xp >=11;

    A = 45;

elseif xp <= 10 && xp >=6;

    A = 30;

elseif xp <= 5 && xp >=1;

    A = 15;
end

if xp == 1|| xp == 6 xp == 11 xp == 16 xp == 21;

    M = 1;

elseif xp == 2 xp == 7 xp == 12|| xp == 17|| xp == 22;

    M=2;
elseif xp == 3 || xp == 8 || xp == 13 || xp == 18 || xp == 23;

    M=3;

elseif xp == 4 xp == 9 xp == 14 xp == 19 xp == 24;

    M=4;
elseif xp == 5 || xp == 10 || xp == 15 || xp == 20 || xp == 25;

    M =5;

end

if val== 0; M = 1; A = 0; end

%% display

fprintf('The setting that best fits your distance is %0.0f degrees and the %0.0fº string position, which wil give you %0.2f feet', A, M, C);

(DOES NOT WORK)(BELOW)

V = [13.36 12.37 11.36 12.40 10.30 11.43 7.70 9.19 4.60 6.66];

val = input('Choose a distance between 0 and 36 feet \n');

tmp = abs(V-val);

[xp xp] = min(tmp);

C = V(xp);

%% conditional

if xp <= 10 && xp >=9;

    A = 75;

elseif xp <=8 && xp >=7;

    A = 60;

elseif xp <= 6 && xp >=5;

    A = 45;

elseif xp <= 4 && xp >=3;

    A = 30;

elseif xp <= 2 && xp >=1;

    A = 15;

end

if xp == 1|| xp == 6

    M=1;

elseif xp == 2 xp == 7;

    M=2;

elseif xp == 3 xp == 8;

    M=3;

elseif xp == 4 xp == 9;

    M=4;

elseif xp == 5 xp == 10;

    M=5;

end

if val== 0; M = 1; A = 0; end

%% display

fprintf('The setting that best fits your distance is %0.0f degrees and the %0.0fº string position, which wil give you %0.2f feet', A, M, C);

I've never seen %0.0f and don't know what you're thinking. Just use %f or something without zeros in it. If you want integers, use %d.

[Stephen23]

I don't know how '%0.0f' could be useful, but '%.0f' can be useful to keep the length of the output correct, e.g. when it should be equal to the number of digits:

>> sprintf('%d',1e19)
ans =
1.000000e+19
>> sprintf('%.0f',1e19)
ans =
10000000000000000000

This is sometimes a more reliable way to count digits than log10 or the like.
