getBudget

Obtain budget constraint bounds from portfolio object

Use the getBudget function with a Portfolio, PortfolioCVaR, or PortfolioMAD object to obtain budget constraint bounds from portfolio objects.

For details on the respective workflows when using these different objects, see Portfolio Object Workflow, PortfolioCVaR Object Workflow, and PortfolioMAD Object Workflow.

Syntax

[LowerBudget,UpperBudget] = getBudget(obj)

Description

example

[LowerBudget,UpperBudget] = getBudget(obj) obtains budget constraint bounds from portfolio objects.

Examples

collapse all

Given portfolio p with the default constraints set, obtain the values for LowerBudget and UpperBudget.

p = Portfolio;
p = setDefaultConstraints(p, 5);
[LowerBudget, UpperBudget] = getBudget(p)
LowerBudget = 1
UpperBudget = 1

Given a PortfolioCVaR object p with the default constraints set, obtain the values for LowerBudget and UpperBudget.

p = PortfolioCVaR;
p = setDefaultConstraints(p, 5);
[LowerBudget, UpperBudget] = getBudget(p)
LowerBudget = 1
UpperBudget = 1

Given a PortfolioMAD object p with the default constraints set, obtain the values for LowerBudget and UpperBudget.

p = PortfolioMAD;
p = setDefaultConstraints(p, 5);
[LowerBudget, UpperBudget] = getBudget(p)
LowerBudget = 1
UpperBudget = 1

Input Arguments

collapse all

Object for portfolio, specified using Portfolio, PortfolioCVaR, or PortfolioMAD object. For more information on creating a portfolio object, see

Data Types: object

Output Arguments

collapse all

Lower bound for budget constraint, returned as a scalar for a Portfolio, PortfolioCVaR, or PortfolioMAD input object (obj).

Upper bound for budget constraint, returned as a scalar for a Portfolio, PortfolioCVaR, or PortfolioMAD input object (obj).

Tips

You can also use dot notation to obtain the budget constraint bounds from portfolio objects.

[LowerBudget, UpperBudget] = obj.getBudget;
