why is this not outputting the correct values

triangle:1

Side A: 3

Side B: 3

Hypotenuse: 6

Side A: 3

Side B: 6

Hypotenuse: 4

triangle:2

Side A:

Side B: 6

Hypotenuse: 6

Side A: 4

Side B: >>

this is the output when I run this script where as I expected to get only two outputs of a's and such, also where could the code have gotten so many values of 3.

pythtrips=[3 4 5;6 8 10]
for      i=1:size(pythtrips,1) 
    e=pythtrips(i:1);
    f=pythtrips(i:2);
    g=pythtrips(i:3);
             fprintf('triangle:%d\n',i)
    fprintf('Side A: %d \nSide B: %d \nHypotenuse: %d \n' ,e,f,g)
end

There is a syntax error, in that you used a colon operator ‘:’ instead of a comma in the ‘pythtrips’ references. The syntax is ‘legal’ in the sense that the colon operator creates a vector (so it would not have thrown an error), however its behaviour was not what you intended.

Try this —

pythtrips=[3 4 5;6 8 10]

pythtrips = 2×3

3 4 5 6 8 10

for      i=1:size(pythtrips,1) 
    e=pythtrips(i,1);
    f=pythtrips(i,2);
    g=pythtrips(i,3);
             fprintf('triangle:%d\n',i)
    fprintf('Side A: %d \nSide B: %d \nHypotenuse: %d \n' ,e,f,g)
end

triangle:1

Side A: 3 
Side B: 4 
Hypotenuse: 5 

triangle:2

Side A: 6 
Side B: 8 
Hypotenuse: 10

this was exactly the case much appreciated
