Polynomial Order

The highest order power in a univariate polynomial is known as its order (or, more properly, its polynomial degree). For example, the polynomial
 P(x)=a_nx^n+...+a_2x^2+a_1x+a_0
is of order n, denoted degP(x)=n.





Debugging in Octave

http://techlogbook.wordpress.com/2008/04/08/debugging-in-octave/


debug_on_warning(1);
debug_on_error(1);

this is to enter debug mode in Octave whenever a warning or error occurs.
To add a breakpoint, use

where 1 is the line number where you want to stop.
To go to next line, type
dbnext
To step into type
dbstep
To continue running, type
dbcont
to see the variable value, just type the name of the variable.
