New in Casyopee 3.2.6 (Dec 18, 2014)
- Interrupting Maxima:
- If Casyopée is expecting a result from Maxima for too long a time (adjustable in the Options dialog), a message invites you to continue to wait (Yes) or stop (No).
- This happens in case a command in Casyopée starts a very complicated calculation in Maxima, or an infinite loop.
- In previous versions, even after choosing No, it happened that Casyopée did not restart because of the infinite loop. Now, a stop command is sent to Maxima, that returns control to Casyopée.
- The stop command can be sent without waiting for the message, by typing Ctrl-i.
- You can test a Maxima infinite loop by entering the formula 'boucle()' in the "Evaluate Formula" box, choosing the Maxima Entry Syntax.
- Redefining Points:
- This was possible in previous versions.
- A point of a kind (free in the plan, free on an object or fixed) can be redefined into another kind.
- In the figure, the free point p2 plan was dragged on the circumference of a circle C0. Casyopée proposes to redefine the free point (selected) into a fixed point or a free point on the circle.
- This feature is useful in order to avoid redoing a construction after an error in the initial definition. It has been redesigned in order to avoid "crashes". It is still to be used with caution because the recalculation of certain objects can cause difficulties.
- Note: In version 3.2.1, the geometric calculations were not updated. This is done in version 3.2.2
- Geometrical parameters in functions:
- In Casyopée, functions make the connection between geometry and algebra. Thus, a function can
- 1. model a geometric dependency between variables
- 2. be a function whose graphical representation is a given line (modelling a straight line).
- 3. be a function whose graphical representation is the locus of a point (modelling a locus).
- A limitation of previous versions was that the functions were "purely mathematical" which forced models to involve a minimal number of geometric data.
- Model and locus from a parameter
- Regression line
- Deviation from a curve
