MATLAB: Find index of maximum number

max

Hi,

May I know how to write in MATLAB to find the index of maximum number.

M = 13;
[gh_w, ph_w, d_l, pl_d] = getWindData(M, weekday);
maxIndex = max (gh_w(:,M));
H = maxIndex;

I only got the output of maximum value which is 611.5077. Thank.

Read the help for max (always a good thing to read the help!)

What does it say?

There are a couple ways you can do this depending on how you want to deal with repeated values. Here's a solution that finds indices for the 5 largest values (which could include repeated values):

[sortedValues,sortIndex] = sort(A(:),'descend'); 
maxIndex = sortIndex(1:5);

Here's a solution that finds the 5 largest unique values, then finds all elements equal to those values:

sortedValues = unique(A(:));          
maxValues = sortedValues(end-4:end); 
maxIndex = ismember(A,maxValues);
