PsiCorrMatrix (matrix cell range, position, instance)
PsiCorrMatrix is used to specify that this uncertain variable is correlated with a group of other uncertain variables, through a matrix of rank-order correlation coefficients. The first argument, matrix cell range, is the Excel cell range where the correlation matrix is located in the Excel spreadsheet. Position specifies the uncertain variable index in the correlation matrix. Instance is the string name given to the correlation matrix. For further information and examples, see “Inducing Correlation Among Uncertain Variables” in the Frontline Solver User Guide chapter “Mastering Simulation and Risk Analysis Concepts.”
