matlab中M文件for循环求解
题目意思是求 y(i)=(x(i+1)-x(i))/x(i)中的每个y
function y(i)=rk(x)
x=[3.9 5.3 7.2 9.6 12.9 17.1 13.2 31.4 38.6 50.2 62.9 76.0 92.0 106.5 123.2 131.7 150.7 179.3 204.5 226.5 251.4]
for i=1:21
y(i)=(x(i+1)-x(i))/x(i);
end
y
运行结果出现这个 该怎么改
Undefined function or variable 'x'.

函数：
function y=digui(x)
n=length(x);
for ii=1:n-1
y(ii)=(x(ii+1)-x(ii))/x(ii);
