Hello,
Considering the plotting functions (defined with "if" ) and two-column matrices here is a continued discussion about that. It seems that the "if" will not work but the function defined via relation operation will work. Here is the picture

The two plots should be basically the same. Here the plot on the right is Ok, and on the left is not working. Pay attention that the plotting has been fixed in v0.85_3578 (see
here )
The same problem will be wrong in v0.85_3545

BTW, it seems that the integration of noncontinous functions will work when defined with relational operators (see the
example) Regards
Radovan
