But, what's the basic approach?  Is your program going to iterate on x to find the exact maximum?  

Or, are you simply going to throw a vector of x's at the function and pick the one that has the highest value?  

Or, would you use Maximize?  which is like given-find, you define guess values, which you should pick from a plot of the function, use maximize(f,x)

IRstuff -

I have assigned the function Mx over the range of x from 0 to L a series of piecewise equations.  

I have plotted the function Mx(x) and can find graphically the max value as well as simply printing out the contents of the Mx(x) and cursor through them.  

But I would like to have another variable, say MaxM that reports the maximum value in Mx(x) automatically without any user input.

I hope that helps.
