MATLAB: Find max value position

findmax

Hi,

I am trying to sort out a problem where I got 210 rows in 1 column, which variable is called 'Force1' and I need to find the position of the max value. I tried the next code:

x=find(max(Force1))

The actual value is in row 170, however, matlab gives me x=1.

Then I tried to apply this one:

x=find(max(Force1))

and result is x= to 210 rows where first one is the max value and then 0

Thank you

x=find(Force1==max(Force1))

[junk, index] = max(Z(:,1));

MATLAB: Max

No.

You can, however, use

[distmax, idx] = max([dist1 dist2 dist3])

and then idx will indicate which index in to the [dist1 dist2 dist3] matrix was the maximum. To figure out which of the variables that came from, you would need to know the size()'s of the variables.

It would be easier if you used

[distmax, idx] = max([max(dist1(:)), max(dist2(:)), max(dist3(:))])

and then idx would indicate which variable number the max was found in; relating the variable number to the variable name is a different matter.

Plain

[distmax, idx] = max([dist1 dist2 dist3])

is the abbreviation for the above for the special case where dist1, dist2, and dist3 are all guaranteed to be scalars (something your question does not allow us to assume).

Question: what do you want to happen if the identical maximum value exists in more than one of the variables?
