I found excel-works derivative functions quite useful. I was particularly pleased with the prompt response for assistance when I required some technical issues to be resolved. I hope the support will remain. It’s quite pleasing to know the company is there when you need them.

Im Rahmen meiner Doktorarbeit im Fach VWL verwende ich das Calculus Add-In von Excelab um Optimale Steuerungsprobleme zu lösen. Ich bestätige, dass ich mit dem Produkt sehr zufrieden bin, denn es bietet mir weit mehr Konfigurationsmöglichkeiten und Modellierungsoptionen als herkömmliche Solver. Zudem ist der Support sehr schnell und zuvorkommend.

I have used the products from ExceLab in the context of my PhD. I find it very robust and reliable. I honestly want to highlight the very efficient help support from ExceLab. They are very proactive and quick providing support, giving the customer support and the feedback to efficiently solve the problems/challenges.

I was working on my multi-equation coupled PDEs model and used a lot of software to solve the problem. They were very complex and not giving a desirable solution. and biggest problem using that software was there is no technical support if I face any error. But after using excel-works pdasolver to solve the model I am very happy. It is easy to learn and support provided by the admin staff is very nice. If anyone working on multi PDEs equation problems, just try this one you will love this solver.

I have used the PDSolve and ODSolve features of Excelab. These are truly robust solvers for a large class of highly nonlinear problems with multiple dependent variables. To my knowledge, this program is the first Excel add-in ever that enables rigorous numerical solution of systems of differential algebraic equations, while being fully contained in Excel. While commercial programs are available, the ability to have our models solved fully in Excel offers a host of practical advantages. In my case, being the sole PDE-system-modeler in a large team of scientists and engineers tapping into model predictions rather frequently, the benefits of having (a) the model in a quick-turn-around-type, (b) the ability to share models and results in a highly familiar platform, (c) the ability to interface with test data with minimal processing, combined with near-zero learning-curve in using the program, have compelled me to break from the past and put in the effort to move our models to Excelab. While there are still things that could be done to improve the software, what we have today is already a big leap. Overall, I would strongly recommend modelers to take advantage of this software. Needless to say that it is a must-have for graduate students. Another main positive would be detailed technical support from personnel with a thorough knowledge of the software as well as ample experience in numerical solutions.
