Using the penalty function method, the solution of nonlinear programming problems can be transformed into solving a series of unconstrained extremum problems. This method is also referred to as the Sequential Unconstrained Minimization Technique, abbreviated as SUMT. The idea behind the penalty function method for solving nonlinear programming problems is to construct an augmented objective … Read more
3.Characters and Strings In MATLAB, several characters (Character) can form a string (String). A string is considered a row vector, and each character in the string (including space characters) is stored in each element of this vector in its ASCII form, although its visible representation remains readable characters. The string type plays a very important … Read more
