If instead of double and subs functions used above, If I had hard-coded the complete symbolic expression for FuncVal and gradVal using qvalue as fixed parameters, then optimization gets completed in less than 10% of the time.

GradVal= double(subs(DCritnGradF,)) ДЄs per profiling tool, more than 95% of optimization time is spent in evaluating lines of code pertaining to FuncVal and gradVal. I have a seperate function file 'Objfungrad', provided below, which fmincon can tap in to for calculating function value and gradient for any given value of x function = Objfungrad(x)ДЇuncVal = double(subs(DCritnF,)) The MATLAB command sqrt(2) returns a floating-point decimal number: ans 1.4142 On the other hand. The following example illustrates the difference between a standard MATLAB data type, such as double, and the corresponding symbolic object. This revised version brings the text completely up to date with the 2019a. These include addition of live scripts, new plotting commands, and major changes to the Symbolic Math Toolbox. Options for using gradient specified (fmincon code skipped here) Symbolic Math Toolbox uses symbolic objects to represent symbolic variables, expressions, and matrices. Since the third edition of Differential Equations with MATLAB first appeared in 2012, there have been many changes and enhancements to MATLAB and Simulink. %fmincon code to optimize DCritn using different start values of x. Xstart= % supplying start points for the optimization %bunch of symbolic computations to arrive at symbolic form of DCritn which is the objective function (see end result after signature) DCRGrad = jacobian(DCritn,x).' %Gradient of the the objective functionДCritnF = subs(DCritn,q,qvalue.') %DCritn objective function specific to qvalueДCritnGradF = subs(DCritnGrad,q,qvalue.') %Gradient of objective function as per qvalue In order to do the optimization, I supply different start points for x and use different set of algorithms like interior point, SQP etc to see which one generates best possible local mimima. Very basic step by step instructions would be appreciated.

I know that it was included, but I am not sure how to get to it. Here q1 and q2 are parameters and x1/x2 are the decision variables.ДЇor any given value of q1 and q2, like let's say 0.6 and 0.3, I try to find the values of x1/x2 for which DCritn is minimum. Hi I have a student version of Matlab, and I need to use symbolic toolbox, but I dont know how to go about installing it. The objective function (DCritn) is listed in the end of this question for reference. The objective function I have is quite complex, based on a bunch of matrix computations (transpose, multiplication, inverse and finally determinant) using the gradient of function in equation 11 of. Details: Im working on global optimization of nonlinear and nonconvex functions by supplying different start points for the decision variables through a For Loop (only have the optimization toolbox in matlab and dont have the global optimization toolbox so simulating multistart functionality).
