matlab中索引超过维度 索引超出矩阵维度怎么解决？

索引超出矩阵维度。

出错 reduceEI (line 3)

if any(M(1,:))

出错 EIsum (line 4)

f=reduceEI([[zeros(max(Msize(1),Nsize(1))-Msize(1),Msize(2));M],[zeros(max(Msize(1),Nsize(1))-Nsize(1),Nsize(2));N]]);

出错 ClassDescribe (line 9)

f1=EIsum(f1,f2);

出错 AFS_Iris_classify (line 33)

DescribeClass{k1}=ClassDescribe(XAttribute,ClassLength+1,ClassLength+ClassNum(k1));

求大触帮助，查了好多，关于这个“索引超出矩阵维度”到底应该怎么改代码？有时候输入数据量小一些就不会出现超出维度的情况，为什么啊？
