MATLAB: Display rational numbers using fprintf

fprintf

I am using fprintf to write my answers to a file. I have numbers such as: 3/7,3/11,6/37… I tried different formats but every time it always changed it to a numeric value. Then I tried format rat before fprintf. This didn't work neither. How can I display a rational number using fprintf?

Best Answer

T = 1/3;
fprintf('The number is:  %s\n',strtrim(rats(T)))

MATLAB: Vectors/rational numbers

a(1)=5040;
a(2)=17;
b(1)=22;
b(2)=342920;
res = r_mul(a,b)
function r = r_mul(a,b)
M = a(2)*b(2); %finding common denominator
N = times(a,b); %multiplying the two fractions
C = gcd(N,M); %cancelling common factor
X = N./C; %simplifying fraction

Y = M./C; %simplifying fraction
r = [X(1),Y(1)]; %final answer
end
