Dear Users,
1. A new function VariableWeight has been introduced:
Usage: VariableWeight[element, keyword ,v_] := expression
where the default weight for matching with element:keyword is passed in v_, and
expression should return a modified value of weight. If non-real is returned,
the default weight is used.
Example: VariableWeight["QF","K1",v_]:= 0.1*v;
reduces the weight of QF1:K1 to 1/10 of the default value.
The weight also affects the step size of the numerical derivative
of the response. A smaller weight makes the step size larger.
VarableWeight only acts for variables used in the matching with the
FREE command.
2. The default weights for some keywords such as VOLT have been defined to be reasonable for usual cases.
