I have a numeric function which for the sake of simplicity resembles the following:
x = linspace(1:100) ;
y = sin(x) ;
I would like to know if there is a function in matlab where it returns the zeros of the above (presumably based on the sign change of adjacent elements).
EDIT: The function as I say above is numeric, hence cannot be analitically expressed (i.e. sin cosing or whatever) as it is shown in my example. I used the above example just to create to numeric vectors.
