Hello, I have a question about Clear Fontion. For scalar Number there's no problem with Clear Function. But with Matrices and Vector Clear Function do not work. Indeed, after used Clear Function with matrices , I can't redefined the matrice variable wich is cleared like a matrice. I have to redefined the variable like a scalar end then like a matrice.

- Clear does not work at all in my case ( running mono-build from windows, with the void file named "portable.version" ) - What's worst: I've noticed that if a plugin is disabled by the user, SMath ignores this action when recalculating the worksheet and the plugin still works. Besides the plugin is shown as enabled when the program is restarted. Please confirm this issue. Edited by user 19 June 2013 04:20:20(UTC)

Sebast3337 I can't reproduce the issue (see the screenshot), could you attach an example (worksheet and screenshot)?

I think this behavior is by design. best regards, Davide Edited by user 19 June 2013 07:42:15(UTC)

Apparently I was using the plugin functions incorrectly, so everything works fine including the disable function in the current session. I was putting Clear() without an equal, so in the above example Clear(A) does not work, I should have written Clear(A)= Edited by user 19 June 2013 10:12:28(UTC)

Confirmed and explained in the attachment. Clear() deletes the value of a variable but the type is set to line(). Element assignment to line()-variables outside the existing range generates unpredictable results. If you want to do matrix element assignment with a cleared variable then you have to change the type first by assigning a (possibly empty) matrix. Edited by user 22 June 2013 09:52:18(UTC)
