Use the Optimization VIs located on the Functions»Analyze»Mathematics»Optimization palette to determine local minima and maxima of real 1D or n-dimension functions. You can choose between optimization algorithms based on derivatives of the function and algorithms working without these derivatives. You also can use special methods like Linear Programming, Levenberg-Marquardt in symbolic form, Pade, and Chebyshev Approximation.
Click the icons for VI descriptions.
An overview of the optimization routines is shown in the illustration below.
