Examples do not compile

Using "kalman_minimal" example I get tons of error. I tried to hot-fix the issue (array -> matrix etc.) but simply failed.

[...many more errors...]

Try using other versions of the library BasicLinearAlgebra. I was trying the last one and i got error. Version 3.2 should work!

It works for me, changing BasicLinearAlgebra to v 3.2

Thanks!
