Hi everyone,
Suppose I have a matrix:
a = [3;1;4;2;3;4;1;4;3;1;2;4];
Then I want matrix b to be:
b = [3;6;8;12]
  • Matrix b is included the rwo number of all max number in the matrix a, e.g. row(3)=4; row(6)=4; row(8)=4; row(12)=4;
Can anyone please help me?

a = [3;1;4;2;3;4;1;4;3;1;2;4];
idx=find(ismember(a,max(a)))

Use the find function:
a = [3;1;4;2;3;4;1;4;3;1;2;4];
b = find(a == max(a))
yields:
b =
3
6
8
12
