Detailed Description

A structure representing a mathematical value/expression/result.

A MathStructure can both be container representing an operation with an ordered list of children or simple value representing a number, , variable etc. The children of a container might be of any type, allowing a tree-like nested structure.

These are the most common conatiner/operation types:

Also available are containers representing logical and bitwise operations. Subtraction is represented by an addition structure with negated children and division by a multiplication structure with inverted children. Matrices is represented by a vector with vectors as children.

For formatted structures, the following types is also available:

The following value types are available:

To create a MathStructure, you can either create a simple structure using the constructors and then expanding it with structural operations, or use the parse or calculation functions of the global Calculator object to convert an expression string.

The expression "(5x + 2) * 3" can be turned into a MathStructure either using

 MathStructure mstruct = CALCULATOR->parse("(5x + 2) * 3");
or
 MathStructure mstruct(5);
 mstruct *= CALCULATOR->v_x;
 mstruct += 2;
 mstruct *= 3:
The first variant is obviously simpler, but slower and allows less control.

Then, to evaluate/calculate/simplify (whatever) a structure, eval() should normally be used. The EvaluationOptions passed to eval() allows much control over the process and the outcome.

 EvaluationOptions eo;
 mstruct.eval(eo);

After that, to display the result, you should first format the structure using format() and then display it using print(), passing the PrintOptions to both.

 PrintOptions po;
 mstruct.format(po);
 std::cout << mstruct.print(po) << std::endl;

Most low-level functions expect the structure to be unformatted och require that unformat() is called after an expression string has been parsed or format() has been called.

To access a child structure either the [] operator or the safer getChild() can be used. Note however that the index passed to the operator start at zero and the index argument for getChild() starts at one.

 MathStructure mstruct(5);
 mstruct += 2;
 std::cout << mstruct.print() << std::endl; // output: "5 + 2"
 std::cout << mstruct.getChild(1)->print() << std::endl; // output: "5"
 std::cout << mstruct[1].print() << std::endl; // output: "2"

MathStructure uses reference count for management of objects allocated with new. Call ref() when starting to use the object and unref() when done. Note that the reference count is initialized to 1 in the constructors, so ref() should not be called after the object creation. This system is used for all child objects, so the following is perfectly legal:

 MathStructure *mchild_p = mstruct->getChild(1);
 mchild_p->ref(); // mchild_p reference count = 2
 mstruct->unref(); //mstruct reference count = 0, mstruct deleted, mchild_p reference count = 1
 (...)
 mchild_p->unref(); // mchild_p reference count = 0, mchild_p deleted
