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: Dependent argument as user defined random variable
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Argument X = new Argument("X", "5*[Uni]+1");
Expression e = new Expression("X", X);
mXparser.consolePrintln("Res. 1: " + e.getExpressionString() + " = " + e.calculate());
mXparser.consolePrintln("Res. 2: " + e.getExpressionString() + " = " + e.calculate());
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ArgumentPtr X = new_Argument("X", "5*[Uni]+1");
ExpressionPtr e = new_Expression("X", X);
mXparser::consolePrintln("Res. 1: " + e->getExpressionString() + " = " + e->calculate());
mXparser::consolePrintln("Res. 2: " + e->getExpressionString() + " = " + e->calculate());
Code result
[mXparser-v.5.2.1] Res. 1: X = 4.645440222397596
[mXparser-v.5.2.1] Res. 2: X = 5.268153720003576
Case 2: User defined function as user defined random variable – random walk example
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Function rWalk = new Function("rWalk(n) = sum( i, 1, n, rList(-1,1) )");
Expression e = new Expression("rWalk(20)", rWalk);
mXparser.consolePrintln("Res. 1: " + e.getExpressionString() + " = " + e.calculate());
mXparser.consolePrintln("Res. 2: " + e.getExpressionString() + " = " + e.calculate());
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
FunctionPtr rWalk = new_Function("rWalk(n) = sum( i, 1, n, rList(-1,1) )");
ExpressionPtr e = new_Expression("rWalk(20)", rWalk);
mXparser::consolePrintln("Res. 1: " + e->getExpressionString() + " = " + e->calculate());
mXparser::consolePrintln("Res. 2: " + e->getExpressionString() + " = " + e->calculate());
Code result
[mXparser-v.5.2.1] Res. 1: rWalk(20) = 4.0
[mXparser-v.5.2.1] Res. 2: rWalk(20) = -2.0
