对于计算机科学作业,我的目标是将字符串(罗马数字)转换为整数.我要在Matlab中编写一个函数来完成这个.我的代码如下所示.

function [x] = roman2decimal(s)
s1 = substr1(s,1);
s2 = substr2(s,2,2);
s = substr2(s, 3, numel(s));
sum = 0;
if (s1~='')
%Case I - if any of these conditions are true
if (s1=='C' && s2=='M')
    sum = sum + 900;
end
if (s1=='C' && s2=='D')
    sum = sum + 400;
end
if (s1=='X' && s2=='C')
    sum = sum + 90;
end
if (s1=='X' && s2=='L')
    sum = sum + 40;
end
if (s1=='I' && s2=='X')
    sum = sum + 9; …
