matlab 帮忙看下哪有问题,怎么改,急用呀
??? Output argument "i1" (and maybe others) not assigned during call to "E:\matlab\matlab1\work\yh.m (yh)".

Error in ==> yh at 2
S4=0;
什么意思呀???

function [h,l]=sc
p=(fix(125*rand(1,14))*5+20)%20-650之间的5的倍数
l=fliplr(sort(p));
ll=l/2;
lll=ll.*ll;
h=(105625-lll).^0.5;
while h(1)<13
    p=(fix(125*rand(1,14))*5+20)%20-650之间的5的倍数
    l=fliplr(sort(p));
    ll=l/2;
    lll=ll.*ll;
    h=(105625-lll).^0.5;
end
