I am trying to write a program to perform the laguerre method of finding roots of polynomials. To get me started i have found various texts to help. One of the texts demonstrates code for a very similar problem however it uses an undefined function 'laguer'. Is this a function from C no longer used in C++, or have the authors simply not defined it?
It is a possibility that i am barking up the wrong tree with this one, and need to take a different starting point, any suggestions on a good place to start, or relevant resources?
