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: Solve 2x-4 = 0 for x in [0, 10]
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("solve( 2*x - 4, x, 0, 10 )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("solve( 2*x - 4, x, 0, 10 )");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );
Code result
[mXparser-v.5.2.1] Res: solve( 2*x - 4, x, 0, 10 ) = 2.0
Case 2: Solve cos(x) = 0 for x in [0, pi]
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("solve( cos(x), x, 0, pi )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("solve( cos(x), x, 0, pi )");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );
Code result
[mXparser-v.5.2.1] Res: solve( cos(x), x, 0, pi ) = 1.57079633
Case 3: Solve cos(x) = 0 for x in [pi, pi] (root not bracketed)
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Expression e = new Expression("solve( cos(x), x, -pi, pi )");
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ExpressionPtr e = new_Expression("solve( cos(x), x, -pi, pi )");
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );
Code result
[mXparser-v.5.2.1] Res: solve( cos(x), x, -pi, pi ) = -1.57079633
Case 4: Solve x-y = 0 for x in [0, 10] and y = 4
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Argument y = new Argument("y = 4");
Expression e = new Expression("solve( x-y, x, 0, 10 )", y);
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ArgumentPtr y = new_Argument("y = 4");
ExpressionPtr e = new_Expression("solve( x-y, x, 0, 10 )", y);
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );
Code result
[mXparser-v.5.2.1] Res: solve( x-y, x, 0, 10 ) = 4.0
Case 5: Solve sin'(x) = 0 for x in [0, pi]
Java/C# code
// JAVA: import org.mariuszgromada.math.mxparser.*;
// C#: using org.mariuszgromada.math.mxparser;
// ...
Argument x = new Argument("x");
Expression e = new Expression("solve( der( sin(x), x ), x, 0, pi )", x);
mXparser.consolePrintln("Res: " + e.getExpressionString() + " = " + e.calculate() );
C++ code
#include "org/mariuszgromada/math/mxparser.hpp"
// ...
ArgumentPtr x = new_Argument("x");
ExpressionPtr e = new_Expression("solve( der( sin(x), x ), x, 0, pi )", x);
mXparser::consolePrintln("Res: " + e->getExpressionString() + " = " + e->calculate() );
Code result
[mXparser-v.5.2.1] Res: solve( der( sin(x), x ), x, 0, pi ) = 1.57079633
