islocalmax identifies all local maxima (or peaks) in the input data and follows these steps to compute the prominence of each local maximum. The prominence of a local maximum measures how the peak stands out with respect to its height and location relative to other peaks. Draw a horizontal ...
The symbolicmaxfunction returns an unevaluated expression. The expression is reduced by eliminating arguments that do not represent maximum values. Largest Element InvolvingNaN Create a symbolic vector and compute its maximum, excludingNaNvalues.
