As a conclusion, we can say that this software offers strong possibilities. The utilisation is pretty easy for simple problem. For advanced problem, it is more complex. Moreover, you can access to introduction course on internet. But for advanced functions, it is more complex for find books or article. Moreover, there is some books and user manual but there are paying and expensive. There is a lot of similarities with Matlab. The graphic interface on scilab is less advanced : it is a simple interface, less developed than Matlab. For example, computation on matrix have similar syntax. Nevertheless, some functions proposed in scilab are limited or complex for a beginner. For example, the matlab to scilab translator is not very efficient and require strong skills of matlab. Some functions such as graphics or data interfacing are complex at the beginning.
