ToВ call the polyroots (and other polynomial functions) from any Python functionВ the following line must be added toВ the Python code module: All the functions will be available in the same way as the built-in Excel functions. Details of the Python code for the functions are given below, butВ all this is included inВ the polynomial.py module, and once thatВ has been installed no further coding is required. See: Installing Python, Scipy andВ PyxllВ for more details.

Add: polynomial.py to the вЂњmodules =вЂќ section of theВ PyXll pyxll.cfg file (example included in the download file).Note that once the py_polynomial.py module has been installed the functions may be called from any Excel worksheet, including. The download file also includes the spreadsheet py_Polynomial.xlsb, including the examples illustrated below, and VBA based polynomial functions.

I think you really need to just face the learning curve and learn to use Mathcad well enough to use vectors and matrices.In previous posts in this series I have looked at translating VBA functions to solve quadratic and cubic equations, but the Python numpy library has a polyroots function that will solve polynomials of any degree, and will also handle polynomials with complex coefficients.ДЇull open source code for all the functions described in this post, as well as the py_Quadratic and py_Cubic functions, may be downloaded from py_polynomial.zip. But expect consulting contracts to run in the neighborhood of $1000 per day. If you check their web site they do seem to have consulting services, and these might have access to the Mathcad source code. As to getting Mathsoft to tailor a version of Mathcad for you, that may be possible. But I'm quite sure that 200 unique names is not it.ДЄFAIK the solving and optimization pack does not change the number of arguments allowed in a function (which is the limit you are running into, not a limit on the find itself, wich might well be coded to support more arguments than can be typed), but I don't have that pack.

You haven't posted a sample of the problem (200 variables, to start, is a large number, but since it seems clear that your problem is multiple repetitions of some basic block, you should be able to produce a sample with about 10% of the original), so I can't say precisely what the best organization would be. The fact that you have a large number of sine function reinforces my belief that you don't have 200 truly unique (conecptually) variables, but a small number of variables with many values for each - i.e., a few vectors, or even a single matrix. It clearly implies, if not states, that it is capable of working with 200 variables on this program. Mathcad should consider rewriting their documentation regarding its capabilities on the limit of number of variables. I will of course go back & study very carefully Tom's reply xx(208)etc & come back with questions.ДЄlternatively, is there any way the limiting number of 50 variables can be increased to what I require? Either by purchasing Solving & Optimization Extension pack OR have someone at Mathsoft customize the program so it can accept 200 variable at the Find(x) function.ДЄs always, really appreciate any help you can offer. However I fear the learning curve too high to transpose my problem into vectors. I have looked over Tom's helpful suggestion thread '59 variables' & found that interesting. I have re-appraised my problem & requirements & still definitely require 200 variables for this calculation. (Fourier cannot help in this case, but similar setup.) I have a large number of independent sin(x)functions which truly require 200 variables.
