mXparser is a highly flexible parser of mathematical expressions provided as text. Software delivers easy to use API for JAVA, C# .NET, TypeScript and JavaScript.
The tutorial consists of c.a. 180 live examples from c.a. 40 sections. 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!
mXparser provides a rich collection of built-in math functions, math expressions, and math symbols. Familiarize yourself with the scope and the syntax. Math collection internal help is also available directly from the software – see the tutorial and the API documentation for all the details.
Did you find the software useful?
Expression e = new Expression("2+3");
e.calculate();
👍
A calculator supporting parenthesis...Expression e = new Expression("2+(3-5)^2");
e.calculate();
👍
You care about predefined constants...Expression e = new Expression("2*pi");
e.calculate();
👍
You need to define your own constants...Constant tau = new Constant("tau = 2*pi");
Expression e = new Expression("3*tau", tau);
e.calculate();
👍
You enjoy using many built-in functions...Expression e = new Expression("sin(2*pi)");
e.calculate();
👍
You do not limit yourself to unary functions...Expression e = new Expression("gcd(2,5,10,30)");
e.calculate();
👍
What about user defined arguments...Argument x = new Argument("x = 5");
Expression e = new Expression("sin(x)", x);
e.calculate();
👍
You are considering dependent arguments...Argument x = new Argument("x = 5");
Argument y = new Argument("y = 2*x", x);
Expression e = new Expression("sin(y)", y);
e.calculate();
👍
You need to apply some logic...Argument x = new Argument("x = 5");
Expression e = new Expression("if(sin(x) > 5, 1, 0)", x);
e.calculate();
👍
Yes, you are right, there is a support for Boolean algebra!Expression e = new Expression("5=6");
e.calculate();
👍
And for binary relations as well!Expression e = new Expression("5 <= 6");
e.calculate();
👍
mXparser is cool! But this is only the beginning, we are just warming up! You want to play with iterated operators...Expression e = new Expression("sum(i, 1, 10, 2*i^2 + pi)");
e.calculate();
👍
You want to iterate differently by not necessarily whole numbes...Expression e = new Expression("prod(i, 1, 5, i, 0.5)");
e.calculate();
👍
You want to have more fun with math...Argument x = new Argument("x = pi/2");
Expression e20 = new Expression("sum(n,0,10,(-1)^n*(x^(2*n+1))/(2*n+1)!)", x);
e.calculate();
👍
You still want more fun with calculus operations, i.e. differentiation...Argument x = new Argument("x = pi/2");
Expression e = new Expression("cos(x)-der(sin(x), x)", x);
e.calculate();
👍
And definite integrals as well...Expression e = new Expression("2*int(sqrt(1-x^2), x, -1, 1)");
e.calculate();
👍
mXparser is even cooler! It is time to ask about ... user defined functions...Function f = new Function("f(x,y) = sin(x) + cos(y)");
f.calculate(1,2);
Expression e = new Expression("f(1,2) - 10", f);
e.calculate();
👍
Recursion is your desire...Function f = new Function("f(n) = if( n>0, n*f(n-1), 1)");
f.calculate()
👍
Function Cnk = new Function("Cnk(n,k) = if(k>0, if(k<n, Cnk(n-1,k-1)+Cnk(n-1,k), 1), 1)");
Cnk.calculate()
👍
If anything above matches you then mXparser is a good choice! mXparser can interact with end users as it supports syntax checking.Expression e = new Expression("2+1/a");
e.checkSyntax();
mXparser.consolePrintln(e.getErrorMessage());
