Suppose there are 2 matrices of double type each with same elements, assume

a = [1,0,0,0,1] and

b = [1,0,0,0,0].

Here, the nnumber of different elements is 1(i.e. the last element is different)

and finally it should give the result as, 1/5= 0.2. It means, result = no. of differet elemet / total number of element.

Kindly suggest.

在 MATLAB Online 中打开

diffelements=sum(a~=b)
result=diffelements/numel(a)
