How to Find the Maximum & Minimum Values of a Function?

Find the Maximum and Minimum Value of Quadratic Function

Using MATLAB:The maximum value of a vector and its corresponding index value can be determined using the max function. The first output from the max function is the maximum value of the input vector. When called with two outputs, the second output is the index value. [xMax, idx] = max(x)How to create the variables vMax and ivMax containing the maximum value of the v2 vector and the corresponding index value.
