Math::SymbolicX::Calculator::Command - Base class for Calculator commands
use Math::SymbolicX::Calculator; my $calc = Math::SymbolicX::Calculator->new(); # setup formula to be a Math::Symbolic tree or a transformation... my $assignment = $calc->new_command( type => 'Assignment', symbol => 'foo', object => $formula, ); $calc->execute($assignment);
This class is a base class for commands to the a Math::SymbolicX::Calculator object. Various commands are implemented as subclasses. See below for a list of core Commands and their usage.
Math::SymbolicX::Calculator::Command::Assignment is an assignment of a formula or transformation to a symbol table slot.
Parameters to the constructor:
symbol => the symbol name to assign to object => Math::Symbolic tree or Math::Symbolic::Custom::Transformation to assign to the symbol
Execution of this command returns the following list: $sym, '==', $func where $sym is the name of the modified symbol and $func is its new value.
$sym, '==', $func
$sym
$func
Math::SymbolicX::Calculator::Command::Transformation is a transformation application to a formula stored in a symbol table slot.
symbol => the name of the symbol to modify trafo => Math::Symbolic::Custom::Transformation object to apply shallow => boolean: Set this to true to apply shallowly or to false to apply recursively (default)
Math::SymbolicX::Calculator::Command::Insertion is a replacement of all variables in a formula (in a symbol table slot) by what's found in the symbol table under the corresponding variable names.
symbol => the name of the symbol to modify optional: what => the name of the variable to replace with its symbol table value or '*' for everything Defaults to everything.
Math::SymbolicX::Calculator::Command::DerivativeApplication is the application of all derivatives in a function in a symbol table slot.
symbol => the name of the symbol to modify optional: level => the number of nested derivatives to apply. Defaults to all/any (undef).
Returns a new Command object. Takes named parameters. The only universally mandatory parameter is the type of the command to create. All paramaters are passed thorugh to the constructed of the implementing subclass. That means if type is Assignment, then new will call Math::SymbolicX::Calculator::Command::Assignment-new()> with its arguments.
