Mathcad have a lot of problems, that's well know. Point here is that even Microsoft Excel it's a very good administrative tool, have not enough resoruses to call it as an engineering friend. Take this 3 arguments as an example:
1. Have not complexes. I think that an engineer can't leave a lot of time without it.
2. Excel's Solver do what is called 'optimization on site'. As consequence destroy guess values (this is: optimize, but in the site where guesses are). That's make root finding a mistery after values are rewrited in the same place that guess are.
3. Excel have not provide a way to define functions. I have one general macro, but it is very slow to true applications.
So, no complex numbers, no roots, nor functions. What tool is that?
