I have a program that plot a graph. This graph is like a senoidal curve.
1) I need get the 3 maximum and minimun values of this graph, excluding the highest value.
2) I need too, display the max of a determined interval.
3) And last of all, i need to do the x axis of the graph present more values.

m = [7;1;4;4;12;2;6;10;2];
[temp,originalpos] = sort( m, 'descend' );
n = temp(1:3)
p=originalpos(1:3)
