356 APPENDIX A. <strong>API</strong> REFERENCE A.2.264 Task.sensitivityreport() Task.sensitivityreport(whichstream) Creates a sensitivity report. Arguments whichstream : streamtype Index of the stream. Description: See also Reads a sensitivity format file from a location given by sparam.sensitivity file name and writes the result to the stream whichstream. If sparam.sensitivity res file name is set to a non-empty string, then the sensitivity report is also written to a file of this name. • Task.dualsensitivity Performs sensitivity analysis on objective coefficients. • Task.primalsensitivity Perform sensitivity analysis on bounds. • iparam.log sensitivity Control logging in sensitivity analyzer. • iparam.log sensitivity opt Control logging in sensitivity analyzer. • iparam.sensitivity type Controls which type of sensitivity analysis is to be performed. A.2.265 Task.setdefaults() Task.setdefaults() Resets all parameters values. Description: Resets all the parameters to their default values. A.2.266 Task.solutiondef() isdef = Task.solutiondef(whichsol) Checks whether a solution is defined. Arguments
A.2. CLASS TASK 357 isdef : int Is non-zero if the requested solution is defined. whichsol : soltype Selects a solution. Description: Checks whether a solution is defined. A.2.267 Task.solutionsummary() Task.solutionsummary(whichstream) Prints a short summary of the current solutions. Arguments whichstream : streamtype Index of the stream. Description: Prints a short summary of the current solutions. A.2.268 Task.solvewithbasis() numnz = Task.solvewithbasis( transp, numnz, sub, val) Solve a linear equation system involving a basis matrix. Arguments numnz : int As input it is the number of non-zeros in b. As output it is the number of non-zeros in ¯X. sub : int[] As input it contains the positions of the non-zeros in b, i.e. b[sub[k]] ≠ 0, k = 0, . . . , numnz[0] − 1. As output it contains the positions of the non-zeros in ¯X. It is important that sub has room for numcon elements.
