matlab 求两个矩阵对应位置上元素平均值

矩阵大小一样吗?
如果一样

c=(a+b)/2就可以

>>a = [1 2; 3 4];
>>b = [2 3; 4 5];
>>c = (a+b)/2
>>c =
1.5 2.5
3.5 4.5

result=mean([A;B])%A,B是行向量，否则应先将加个'就可以转成行向量了

MEAN Average or mean value.
For vectors, MEAN(X) is the mean value of the elements in X. For
matrices, MEAN(X) is a row vector containing the mean value of
each column. For N-D arrays, MEAN(X) is the mean value of the
elements along the first non-singleton dimension of X.

MEAN(X,DIM) takes the mean along the dimension DIM of X.

Example: If X = [0 1 2
3 4 5]

then mean(X,1) is [1.5 2.5 3.5] and mean(X,2) is [1
4]

Class support for input X:
float: double, single
