mbcdoe.designconstraint

Properties and methods for design of experiment (doe) design constraint objects

expand all in page

Description

Use these properties and object functions to create and examine doe design constraint objects.

A mbcdoe.designconstraint object represents the design constraint of all possible points for use in an optimal design. Constraints is a property of optimal design generators.

Creation

Create a mbcdoe.designconstraint object using CreateConstraint.

Properties

Design constraint type, specified as an array.

C.Type returns the design constraint type. You can only choose a type when you create the design constraint using CreateConstraint.

You can specify the constraint type during creation by using the Type property, for example:

c = D.CreateConstraint('Type','Linear')

The following table lists the properties available for each constraint type.

Constraint Properties

Constraint TypePropertyDescription
Linear design constraint:
1*Input1 + 1* Input2 + 1* Input3 <= 0		A Matrix for linear constraint (matrix: [1,NumInputs])
b Bound for linear constraint (double)
Ellipsoid design constraint:
Ellipsoid at (Input1=0, Input2=0, Input3=0)		CenterPoint Center of ellipse (vector: NumInputs)
MatrixEllipsoid form matrix (positive semi-definite) (matrix: [NumInputs, NumInputs])
1D Table design constraint:
InputY(InputX) <= InputY max		Table Table constraint (vector)
Breakpoints Breakpoints for rows (vector)
InequalityRelational Operator (enum: {'<=','>='})
InputFactorColumn input symbol (enum: { 'InputX','InputY'})
TableFactorTable input symbol (enum: {'InputX','InputY '})
2D Table design constraint:
InputZ(InputX,InputY) <=InputZmax		Table: Table constraint (matrix) )
RowBreakpointsBreakpoints for rows (vector)
ColumnBreakpointsBreakpoints for columns (vector)
InequalityRelational operator (enum: {'<=','>='})
RowFactorRow input symbol (enum: {'InputX','InputY, 'InputZ'})
ColumnFactorColumn input symbol (enum: {'InputX','InputY, 'InputZ'})
TableFactorTable input symbol (enum: {'InputX','InputY',
'InputZ'}
