When time to choose comes, the cost of the initial investment is often a major criterion for making the decision, but do not forget to take hidden charges in account. The time saved with a trustworthy and complete software program can be considerable. The decision maker will also have to think about former investments: IT migration of complex programs from Matlab to Scilab is not certified and can be very expensive, and sometimes impossible.
Nevertheless, for low complexity level applications or broad-based ones, Scilab is likely to be the more decent solution. Indeed, it can be spread across an entire comapny at no cost to provide a common set of tools to everyone.
Some major industrialists have decided to use both Scilab and Matlab; the first one is used for low level scientific computations whereas the second one is reserved for more challenging programs, often linked to onboard computing.
If you are still hesitating in spite of this advice, you can contact Acsystème’s advisors, who are Matlab and Scilab instructors. They will help you analyze your needs in order to make the right choice.
