Write a MATLAB function file that finds the greatest common
     Write a MATLAB function file that finds the greatest common divisor of two integers. Your function definition line is given as follows:  function gcd=find_gcd (a, b)  where your input variables are integers a and b and your output argument is the returned result gcd. Test your function under the command window to find the gcd of 129 and 15. 
  
  Solution
function gcd1=find_gcd(a,b)
a1=a;b1=b;
while(a~=b)
if(a>b)
a=a-b;
else
b=b-a;
end
end
gcd1=a;
end
OUTPUT:
find_gcd(129,15)
 ans =
 3
>> find_gcd(100,75)
 ans =
 25
