ISmNonLinearLeastSquare.FunctionString

Syntax

FunctionString: String;

Description

The FunctionString property determines calculated function.

Comments

The function can contain:

Explanatory variables names. See the ISmNonLinearLeastSquare.Explanatories property.
Coefficients names. See the ISmNonLinearLeastSquare.CoefficientsOrder property.
Any arithmetic operations and round brackets.
Numbers.

The function expression may get the Fore function implemented in the unit that is sent as follows: <Unit identifier>.<Function identifier>[(Function parameters)]. To do this, determine a repository, in which the unit is searched.

The use of the expression, implemented in the unit, is given in the example for ISmExpressionProvider.Metabase.

Example

The property use is given in the example for ISmNonLinearLeastSquare.CoefficientsOrder.
