matlab为什么出现 Subscript indices must either be real positive integers or logicals.为什么出现>> A=[2 -3 -2;-1 2 1;4 -7 -6];>> C=det(A)Subscript indices must either be real positive integers or logicals. “subscript out of subscript out of range 是什么? matlab中for语句画图,Subscript indices must either be real positive integers or logicals.for ii=0.1:1x=0:100y(ii)=(L-ii*hg)/(ii*hg)*x-G*b/hg;plot(x,y(ii))hold onend出现Subscript indices must either be real positive integers or logicals.这个 matlab运行 >> x=1:0.01:200; >> a=max(x);出现Subscript indices must either be real positive integers orlogicals.程序明显没有问题,在2012b上可以运行,系统版本2010b Run-time error'9':subscript out of Subscript indices must either be real posit... matlab slice 函数,为什么例子也出错?matlab Help中关于slice作图函数,给出了一个例子然后我copy到命令行里,或者.m中试了试,结果就出来了这么个警告:Subscript indices must either be real positive integers or log matlab中,built in function是什么意思?
