How do you convert a roman numeral into decimal using matlab?

Answer 1

x=input('Enter the roman numeral: ','s');

l=length(x);

for(i=1:l)

if(x(i)=='I')

a(i)=1;

elseif(x(i)=='V')

a(i)=5;

elseif(x(i)=='X')

a(i)=10;

elseif(x(i)=='L')

a(i)=50;

elseif(x(i)=='C')

a(i)=100;

elseif(x(i)=='D')

a(i)=500;

elseif(x(i)=='M')

a(i)=1000;

else

disp('Not a valid entry');

end

end

d=a(l);

for(i=l:-1:2)

if(a(i)>a(i-1))

d=d-a(i-1);

elseif(a(i)==a(i-1) a(i)<a(i-1))

d=d+a(i-1);

end

end

disp('The decimal equivalent is: ');

disp(d);
