libpolynomial

libpolynomial is a C library of a polynomial ADT that supports

• addition
• subtraction
• multiplication
• differentiation
• integration

and other useful operations.

Installation

To install the library to the default directory (/usr/local) run:

$ make install

You can customize the directory to which it is installed by overriding $PREFIX:

$ PREFIX=/home/foo make install

Usage

1. Include the polynomial.h header in your program and use the library functions accordingly.

   #include <polynomial.h>
   
   int main(int argc, char **argv)
   {
       Polynomial *p = polynomial_new(2);
       polynomial_set_coefficient(p, 0, 7);
       polynomial_set_coefficient(p, 1, 2);
       polynomial_set_coefficient(p, 2, 3.5);
   
       Polynomial *q = polynomial_new(3);
       polynomial_set_coefficient(q, 0, 1);
       polynomial_set_coefficient(q, 1, 3);
       polynomial_set_coefficient(q, 2, 0.2);
       polynomial_set_coefficient(q, 3, 4);
   
       Polynomial *r = polynomial_add(p, q);
   
       polynomial_destroy(&p);
       polynomial_destroy(&q);
       polynomial_destroy(&r);
   
       return 0;
   }

2. Link the program against the static library and compile it.

   $ gcc foo.c -lpolynomial -o foo

Development

gcc is the only build dependency. To build the library run:

$ make
