Finding the array location in the matrix
显示 更早的评论
Hi everyone,
Suppose I have a matrix:
b = [8;5;9;12]
and:
max(b) = 12 %12 is in the fourth row
I'm looking for a command line which instead of giving me the maximum value, give it to me as a row number (e.g = 4, not 12).
Can anyone help me please?

Hi Mohammad,
If the input is a vector, then you can do the following:
[val,idx] = max(b);
where val will be the maximum value of 12 and idx will be the index of 4. Type help max for more details. (It gets a little more complicated when the input is matrix.)
