3 GiNaC-cint \- An interactive interface for GiNaC based on the Cint C/C++ interpreter
8 is an interactive frontend for the GiNaC symbolic computation
9 framework. It is a tool that lets you write interactive programs in
10 C++ that directly make use of GiNaC's classes and thus a more complete
11 replacement for traditional interactive computer algebra systems than
12 \fBginsh\fP(1) is. Programs may be composed as scripts and later compiled
13 with the native compiler and linked into the system.
16 After startup, ginsh displays a prompt signifying that it is ready to
17 accept your input. All C++ statements are valid as input, extended by
18 GiNaC's numeric or symbolic expressions. E.g.
19 .BR fibonacci(24)/1104;
20 returns a GiNaC object of class
22 , which in this case represents the numeric 42. Symbols are declared by
25 GiNaC> symbol x("x"), y("y"), z;
27 which defines two named symbols and an anonymous one for later usage.
28 All GiNaC methods and functions are available as they would be typed
29 in C++. It is not necessary to explicitly invoke a print command as
30 the last expression is automatically printed:
32 GiNaC> pow(x+y,4).expand();
33 out2 = x^4+4*x^3*y+6*x^2*y^2+4*x*y^3+y^4
35 Statements are generally closed by either when a closing brace
37 matches the first opening brace
44 .SS FUNCTION DEFINITIONS
45 GiNaC-cint must be put into a special mode in order to define a
46 function. This is done with the command
48 After that any function definition in valid C++ syntax may be typed
49 in. It becomes immediatly available for usage.
53 GiNaC> symbol x("x"), y("y"), z("z");
54 GiNaC> ex a = pow(x,2)-x-2;
55 GiNaC> ex b = pow(x+1,2);
58 out1 -2*(1+x)^(-3)*(-2-x+x^2)+(-1+2*x)*(1+x)^(-2)
60 out2 (-2+x)*(1+x)^(-1)
62 next expression can be a function definition
63 GiNaC> ex EulerNumber(unsigned n)
66 > ex generator = pow(cosh(x),-1);
67 > return generator.diff(x,n).subs(x==0);

76 Cint accepts most of K&R and ANSI C/C++ language construct but not
77 perfect. In fact, Cint is not aimed to be a 100% ANSI/ISO compliant
78 C/C++ language processor. It rather is a portable script language
79 environment which is close enough to the standard C++. See the file
81 in your Cint distribution. Please take the time to track down any bug
82 you encounter as far as possible and contact Masaharu Goto
83 <MXJ02154@niftyserve.or.jp> for Cint-related bugs and
84 <ginac-bugs@ginac.de> for any bugs in the GiNaC engine.
