Luc and Ted, thank you for your help and support. I understand the dimensionality part. Indeed most of the equations I need to solve have one unknown.
I am looking to parse the equation from String to matrix form. I was not lucky enough to find any parser that can do this out-of-the-box. As Luc said, it will big project to write a parser that takes any equation as a string, and generate the matrix (2-dimensional array) to feed it into Commons Math. Thank you.
