Syntax ConSet portcons varargin Description Using linear inequalities portcons generates a matrix of constraints for a portfolio of asset investments. The matrix ConSet is defined as ConSet A b . A is a matrix and b a vector such that A PortWts b sets the value where PortWts is a 1-by-number of assets NASSETS vector of asset allocations. ConSet portcons ConstType Data1 . DataN creates a matrix ConSet based on the constraint type ConstType and the constraint parameters Data1 . DataN. ConSet portcons ConstType1 Data11 . Data1N ConstType2 Data21 . Data2N . creates a matrix ConSet based on the constraint types ConstTypeN and the corresponding constraint parameters DataN1 . DataNN. Constraint Type Description Values Default All allocations are 0 no short selling allowed. Combined value of portfolio allocations normalized to 1. NumAssets required . Scalar representing number of assets in portfolio. PortValue Fix total value of portfolio to PVal. PVal required . Scalar representing total value of portfolio. NumAssets required . Scalar representing number of assets in portfolio. See pcpval. 2-182 portcons Constraint Type Description Values AssetLims Minimum and maximum allocation per asset. AssetMin required . Scalar or vector of length NASSETS specifying minimum allocation per asset. AssetMax required . Scalar or vector of length NASSETS specifying maximum allocation per asset. NumAssets optional . See pcalims. GroupLims Minimum and maximum allocations to asset group. Groups required . NGROUPS-by-NASSETS matrix specifying which assets belong to each group. GroupMin required . Scalar or a vector of length NGROUPS specifying minimum combined allocations in each group. GroupMax required . Scalar or a vector of length NGROUPS specifying maximum combined allocations in each group. See pcglims. 2-183 portcons Constraint Type Description Values GroupComparison Group-to-group comparison GroupA required . constraints. GroupB required . .
