下标索引必须是实数正整数或逻辑数

Question

我的matlab函数代码出现以下错误：

？？？下标索引必须是实数正整数或逻辑数。

==> AFA 在 15 时出错 M(k,j) = 均值(T(i:sze,j));

这是问题所在的代码部分：

sz =size(T);
lim = sz(2) - ordre;
M = zeros(sz(1),sz(2));
r= 0;
for j=1:sze,
    k = 1;
for i=1:lim,
    M(k,j) = mean(T(i:i+ordre,j));
    k = k + 1;    
end

for i=lim+1:sz(2),
    M(k,j) = mean(T(i:sz(2),j));
    k = k + 1; 
end
end

Answer 1

以下内容对我有用，没有错误

T = magic(25);ordre = 5; %# I make up some values here
sz =size(T);
lim = sz(2) - ordre;
%# I've added a check here
if lim < 1, error('ordre has to be at most sz(2)-1 (is %i)',ordre);end
M = zeros(sz(1),sz(2));
r= 0;
for j=1:sz(2), %# I needed to change this line (sz(1) works as well)
    k = 1;
for i=1:lim,
    M(k,j) = mean(T(i:i+ordre,j));
    k = k + 1;    
end

for i=lim+1:sz(2),
    M(k,j) = mean(T(i:sz(2),j));
    k = k + 1; 
end

结束
