finding mode without any repeated number?
显示 更早的评论
I am trying to find the Mode of the columns in the Matrix A. My problem is, if there is no similar value in the column, the mode function always returns the lowest possible number. I read the definition of Mode and if there is no number repeated then there should be no mode. In that case, I should be getting No mode or error message. But why do it gets me the lowest number in the column? What is the theory behind the mode() function here?
A=[1.13 2 9 ; 1.12 5 8; 1.17 7 6];
P= mode(A(:,1));
Q= mode(A(:,2));
R= mode(A(:,3));
The values that I get after running the code are -
P = 1.12
Q = 2
R =6

"if there is no number repeated then there should be no mode" Where does it say that?
What I read, in the help for R2018b, is "When there are multiple values occurring equally frequently, mode returns the smallest of those values." So you have 3 modes, and it returns the smallest one, just as the help specifies.
