Mathematica Question: Finding local maximums

[dreiter]

Hi all! This is a generic Mathematica question, which hopefully someone can help me with! :)

I have a set of data points.
I have an interpolating function from those points.
I have a graph of that interpolation function.

The graph goes like Sin^2, and has about 10 peaks. I want to have Mathematica find those 10 peaks. FindMaximum only finds 1 peak. How can I get it to find all 10?

I would use:

Union[Table[FindMaximum[f[x], {x, xInit}], {xInit, xMin, xMax, xStep}]]
