How to solve for polynomial roots using MathScript

[elset191]

Those four lines specifically don't help you directly.  It's an example meant to get you familiar with fzero.  It has been so long since I have used matlab or taken a math class, and I don't know specifically how to solve your problem.  I was replying to your inquiry to get a working example of fzero

Tim thanks for trying - it is the math help I need I am afraid.....

You could write the .m file over and over given each set of coefficients... (I have no idea if this VI outputs the right numbers, you'd have to check that)

Tim - that does in fact work!!  Thank you for that!

This calculation will be done thousands of times in the model I am building - if anyone can suggest a way to get this to work without the file I/O that would be very helpful!

That depends, if you don't want to use Mathscript, this is pretty easy and does not involve file operations.  Eventually you may want to ditch the formula string and use a VI to calculate f(x), but this gets you pointed in the right direction.

Tim and Darin,

Got it!!!  Thank you very much for your help!
