matlab functions for optimization
These matlab functions implement methods for minimizing a function of several variables subject to a set of inequality constraints:
minimize f(x) such that g(x) ≤ 0,
where x is a vector of n design variables,
f(x) is a scalar-valued objective function,
and g(x) is a vector of m constraints.
- Examples of running constrained minimization codes
- ORSopt.m implements an optimized step-size random search algorithm.
- NMAopt.m implements a Nelder-Mead algorithm.
- SQPopt.m implements a sequential quadratic programming algorithm.
- avg_cov_func.m calculates average and coefficient of variation of a random penalized objective function.
- box_constraint.m determines the box constraint scaling factor a>0 to the perturbation vector r from x such that: max(x+ar) < +1 and min(x+ar) > -1
- optim_options.m is needed for ORSopt.m, NMAopt.m, and SQPopt.m
- plot_surface.m plots the cost function as a surface over two of the parameter values, ORSopt, NMAopt, or SQPopt
- plot_cvg_hst.m plots the convergence history for the solution computed by ORSopt, NMAopt, or SQPopt
matlab functions for random variables
These matlab functions can be used to compute probability distribution functions and to generate samples of random variables.
- plotCDFci.m plots the empirical CDF from a sample of data along with the confidence interval of the CDF.
- corr_beta_rnd.m generates a sample of correlated beta values.
- corr_logn_rnd.m generates a sample of correlated log normal values.
- MCS_intro.m illustrates the use of a number of these functions.
