How to Find the Local Maxima of a Function in MATLAB? We can easily determine thelocal maximaof a function in MATLAB using the built-infindpeaks()function. This function allows us to determine thelocal maximaof an input data or a signal. This function takes a data set as a mandatory inpu...
Example 1: Find the points of maxima and minima of a function: y = 2x3 –3x2 + 6 Solution Given function: y = 2x3 –3x2 + 6 Using the second order derivative test to find a function’s maximum and minimum: Taking the first derivative of: y = 2x3 –3x2 + 6 —– (eq 1) ...
How to Find the Inverse of a Function (With Examples) Math: How to Find the Tangent Line of a Function in a Point How to Find the Mean of a Probability Distribution How to Find the Slope of a Line Using the Derivative
Thus, according to the comparison result of the function in two interior points instead of the current segment, we find [l; r]there is a new segment [l' , r']. We now repeat all the steps for this new segment, we again obtain a new, strictly smaller segment, etc. ...
A critical point of a function y = f(x) is a point (c, f(c)) on the graph of f(x) at which either the derivative is 0 (or) the derivative is not defined. Let us see how to find the critical points of a function by its definition and from a graph.
@Imanol Fernandez de arroyabe Zabala,findpeaksis a part of the Signal Processing Toolbox. You need to have the toolbox downloaded and installed to use the function. And since you don't, you get that error message. Alternatively useislocalmaxto find which elements correspond to a local maxim...
