It even has the power to evaluate integrals symbolically – something that I wish I had access to when I was in high school. It will also give the answer to our first quadratic exactly – which is nice. ![]() With the symbolic toolbox, however, calculations such as this are trivial thanks to the solve command If, on the other hand, you wanted to solve the general quadratic a*x^2+b*x+c=0 in terms of a,b and c then you are out of luck using MATLAB on its own. The syntax may look at bit minging at first sight but it does the job and does it efficiently. ![]() For example, if you want to solve the quadratic equation x^2 -2*x -5=0 numerically then basic MATLAB can help you. ![]() The base MATLAB package is strictly numerical and has no support for the symbolic manipulation of equations. If you are new to MATLAB then maybe a quick explanation is in order here. Just over a couple of weeks ago, The Mathworks released the latest version of their main product, MATLAB 2008b, which includes a completely new version of their Symbolic Toolbox.
