Syntax
where
The FE: command can be used to attach functional expectations to
components, and these are accessed when the corresponding
components are the subject of BUILD: , COBUILD: and
ITADJUST: commands to specify expectations for the component
quantities. Otherwise, components are assumed to have zero expectation.
These functionally defined expectations are deleted by the
XFE: command. An expectation store number must be given.
As an example, suppose that we choose to ensure that the
A quantity may be associated with several alternative functional
expectations in different expectation stores. In this case, the index
lists should be compatible, i.e. of the same length. The following
example shows proper use of this facility:
BD>fe : e(1,b.i.j)=sqr (.i)+.j
BD>fe : e(2,b.i.j)=sqr (.i)-.j
