THANK YOU!
The tutorial consists of more than 200 live examples from 50 sections given separately for JAVA, C# and C++. Each of the examples can be copied and run on your own environment. In addition, mXparser provides an extensive collection of over 500 built-in math functions, expressions and symbols. Familiarize yourself with the scope and the syntax. Live testing is the best way to learn. Good luck! 🙂

Below is the code for JAVA, C# (the code for C# is almost identical) and C++. To copy the code, double-click inside the frame.
Case 1: Fibonacci numbers using fast recursion
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
RecursiveArgument fib = new RecursiveArgument("fib(n) = fib(n-1) + fib(n-2)");
fib.addBaseCase(0, 0);
fib.addBaseCase(1, 1);
Expression e = new Expression("fib(10)", fib);
mXparser.consolePrintln("Res 1: " + e.getExpressionString() + " = " + e.calculate());
mXparser.consolePrintln("Res 2: fib(11) = " + fib.getArgumentValue(11));
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
RecursiveArgumentPtr fib = new_RecursiveArgument("fib(n) = fib(n-1) + fib(n-2)");
fib->addBaseCase(0, 0);
fib->addBaseCase(1, 1);
ExpressionPtr e = new_Expression("fib(10)", fib);
mXparser::consolePrintln("Res 1: " + e->getExpressionString() + " = " + e->calculate());
mXparser_consolePrintln("Res 2: fib(11) = " + fib->getArgumentValue(11));
Code result
[mXparser-v.5.2.1] Res 1: fib(10) = 55.0
[mXparser-v.5.2.1] Res 2: fib(11) = 89.0
Case 2: Fibonacci numbers using fast recursion – less convenient, but faster constructor
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
RecursiveArgument fib = new RecursiveArgument("fib", "fib(n-1) + fib(n-2)", "n");
fib.addBaseCase(0, 0);
fib.addBaseCase(1, 1);
Expression e = new Expression("fib(10)", fib);
mXparser.consolePrintln("Res 1: " + e.getExpressionString() + " = " + e.calculate());
mXparser.consolePrintln("Res 2: fib(11) = " + fib.getArgumentValue(11));
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
RecursiveArgumentPtr fib = new_RecursiveArgument("fib", "fib(n-1) + fib(n-2)", "n");
fib->addBaseCase(0, 0);
fib->addBaseCase(1, 1);
ExpressionPtr e = new_Expression("fib(10)", fib);
mXparser::consolePrintln("Res 1: " + e->getExpressionString() + " = " + e->calculate());
mXparser_consolePrintln("Res 2: fib(11) = " + fib->getArgumentValue(11));
Code result
[mXparser-v.5.2.1] Res 1: fib(10) = 55.0
[mXparser-v.5.2.1] Res 2: fib(11) = 89.0
