Be careful with this. I tried to use this toolbox because it was needed to use some of the examples, and I went through a lot of posts trying to solve the problems I had. The final solution that was given to me was that Scilab was meant to be used on a Linux, not Windows environment. Even though they have a Windows version for download. I hope you are using Linux.
Has anyone installed this toolbox ever? I've got some problems when I tried to install on macOS.
