What Is Optimization Toolbox?

fseminfThe vectors or matrices K1, K2, ..., Kntheta contain the semi-infiniteconstraints evaluated for a sampled set of values for the independent variablesw1, w2, ... wntheta, respectively. The two-column matrix, S, containsarecommended sampling interval for values of w1, w2, ..., wntheta, whichareusedtoevaluateK1, K2, ..., Kntheta. The ith row of S contains therecommended sampling interval for evaluating Ki. WhenKi is a vector, useonly S(i,1) (the second column can be all zeros). When Ki is a matrix, S(i,2)is used for the sampling of the rows in Ki, S(i,1) is used for the samplinginterval of the columns of Ki (see “Two-Dimensional Example” on page 8-103).On the first iteration S is NaN, so that some initial sampling interval mustbe determined by seminfcon.Note Because the functions in Optimization Toolbox only accept inputs oftype double, user-supplied objective and nonlinear constraint functions mustreturn outputs of type double.“Avoiding Global Variables via Anonymous and Nested Functions” on page2-20 explains how to parameterize seminfcon, if necessary.OutputArguments“Function Arguments” on page 6-2 contains general descriptions ofarguments returnedbyfseminf.
