Definition of public elements:
class Table : public vector<pair<double,double> >
{
Table();
Table(const Table& t);
Table(const string& filename);
Table(double singlevalue);
Table(double *x,double *y,int n);
virtual ~Table();
Table& operator=(const Table& s);
double value(double l) const;
int read(const string& filename, int ycol=2);
static Table AskUser(const string& prompt,const string& deflt);
static Table AskUser(const string& prompt,double deflt);
}
Class
constructor and assignment operator. When called without
any arguments, the class is considered uninitialized and
an error will occur if a call to value is made. If called with a pointer to a
string, the class will be initialized with the contents
of the first two columns of the file. If a single
double is given, then the table will have a single
constant value. If the constructor is called with two
pointers to double and an integer value n,
then the table will contain n values pointed to by
the arrays.

Function which returns the value of the table at a
particular linearly interpolated point. Successive calls
with the same l do not require new searches and
interpolations; the previously obtained value is always
saved and used if possible. While this function is
declared as const, the contractual const is broken to
enable this feature. The functionality of the class,
however, is not changed by this function.

Function which will read columns 1 and ycol
of a file filename.
Top of Page
Functions which prompt the user for either a value or a
filename.
Example:
Table reflectance = Table::AskUser("Reflectance","reflectance.dat");
