Math::SymbolicX::Calculator - A representation of a Symbolic Calculator
# You probably want to use on of the interfaces instead such as # Math::SymbolicX::Calculator::Interface::Shell use Math::SymbolicX::Calculator; my $calc = Math::SymbolicX::Calculator->new(); my $cmd = $calc->new_command(...); # ... $calc->execute($cmd);
This class represents the state of a symbolic calculator. It is mainly a glorified state hash of variables and their contents.
It can execute commands which are represented by Math::SymbolicX::Calculator::Command objects and which operate on the symbol table on some way.
Returns a new Calculator object.
This method is a short-cut to Math::SymbolicX::Calculator::Command's
new method and creates a new command object which can be executed using the Calculator object.
Executes the command given as first argument. The command should be a Math::SymbolicX::Calculator::Command object. Returns any return values of the command's execution. (This may be a list!)
Accesses the symbol table hash with the symbol name given as first argument. Valid symbol names match the regex
(This is read only.)
First argument must be a symbol name. Accesses the Calculator symbol table to fetch a transformation from it that is saved as the symbol.
If the smybol table contains a transformation in the specified slot, that transformation is returned.
If it contains a formula, it manufactures a transformation from that formula which amounts to replacing the specified symbol with the formula.
If an error occurrs, an error message will be returned instead of a
