Good day and thanks in advance for any help and ideas with my question...

I am a newbie programmer primarily interested in writing simple numerical integrators and root finders and evaluators...

Such as, Euler's Method for approximating integrals and Newton's method for finding roots...Horner's Method for evaluating a polynomail....

So I have some books on the topic of writing the code for the functions (class objects)

which assume that the source function is provided.

Is there a way to have the user input an equation and store it as a string or other, and have that string converted into code ?

I suppose there must be since matlab and others have a way of doing it....

I can only hope that it is not too outside of my understanding..

peace
