function f=isleapyear(year)
sign=0;
if rem(year,4)==0
sign=sign+1;
end
if rem(year,100)==0
sign=sign-1;
end
if rem(year,400)==0
sign=sign+1;
end
if sign==1
fprintf('%d is a leap year.\n',year)
end
运行后显示：??? Input argument 'year' is undefined.
Error in ==> D:\matlab\matlab\work\isleapyear.m
On line 5 ==> if rem(year,4)==0
小弟不知为什么请指点
