Update of MaximaTakeover() (SS-1244, SS-2401)

Achtung: In früheren Versionen des Plugins galt die Übernahme für die ganze Maxima- Sitzung der laufenden SMath-Instanz. In der aktuellen Version erfolgt die Übernahme durch Definitionen der Art int(f,x)=Int(f,x) im aktuellen Rechenblatt oder Anweisungsblock. Damit werden ungewollte Wechselwirkungen zwischen Rechenblättern vermieden.

Note: In former versions the takeover state was set for the whole SMath instance (with side effects between multiple sheets). In the 2017 version of the plugin, the takeover state is done by re-defining the internal functions local to the current sheet or program.

Argumente für die vollständige Umschaltung:

Provide a single argument for complete switching on or off:

Alle Funktionen von Maxima übernommen

All functions are handled by Maxima

Alle Funktionen original SMath (Voreinstellung)

All functions are native SMath (default)

Geben Sie bis zu 5 beliebig kombinierte Funktionen an, die von Maxima übernommen werden sollen:

Provide up to 5 arguments in any combination in order to handle these functions by Maxima.

Keine oder ungültige Argumente sind gleichwertig zum Argument "none".

None or any other non-valid argument is equivalent to "none"

Die Voreinstellung ("none") wird bei MaximaControl("restart") oder MaximaControl("cleanup") wieder hergestellt.

The default ("none") is re-established when MaximaControl("restart") or MaximaControl("cleanup") are called.

- SS-1244/SS-2401: Takeover of SMath functions int(), diff(), det(), sum(), lim() fixed and now on per-document base instead of per-session base. - SS 193: MaximaDefine() now does not add SMath definitions - SS 191: Access to last result with Maxima(%) works - SS 189: Waiting for Maxima response now without time-out - MaximaLog(): Improved formatting - Compatibility with Maxima 5.40.0 (SBCL recommended) - Icon for the Insert> Maxima Menu group - Draw2D() and Draw3D() now can produce PDF vector graphics and have consistent size control with length units or pixels - Settings dialog streamlined - SS 3452: Loop variable in sum(4) is now local (safe use of i) - SS 3460: Translation of # - SS 157: Translation of \ - SS-198: Improved default settings for Draw2D/3D regions

Improved output formatting of MaximaLog()

The same information as before is now displayed in 3 lines instead of 6. The expressions have the correct input and output labels.

SS-189: No time-out any more

Use the "Interrupt processing" button if you want to stop a calculation. To recover you might need to issue MaximaControl("restart")= at the top of the sheet and then re-calculate.

SS-191: Access to last Maxima answer by %

SS-193: Corrected behaviour of MaximaDefine()

Definiert die Variable s in Maxima unter Verwendung des Ausdrucks expr oder des momentanen Werts von s in SMath. Der Wert von s in SMath wird in keinem Fall verändert. Verwendung zum Beispiel zum Setzen von Steuervariablen in Maxima.

Defines symbol s in Maxima using the given expression expr or the current value of s in SMath. s is not re-defined in SMath. This can be used to set control variables inside Maxima.

PDF output in Draw2D and Draw3D

The functions now can generate PNG, PDFand SVG output. PNG is default. The files are always created with random names in the plugin directory and copied to their destination if a filename is given. The format is defined by the filename extension. If you specify just "svg" or "pdf", the actual random file name is returned and can be used for file access in the image region placeholder. Limitations: SVG: text alignment is not correctly displayed in the image region (in inkscape they show up correctly) PDF: specification of a destination file name (not just "pdf") requires the a nightly build of Maxima of 2017-08-16 or newer, found at

Improved image size control for Draw2D and Draw3D

You can specify the image size using a list of two numbers with any SMath length unit. If they are unitless, they are interpreted as pixels. For PDF and PNG, the image region can be reset to this original size using the context menu. Default size is 8 cm x 6,4 cm.

SS-3452: Loop variable in Sum(4) is now local

They are treated as local and won't be re-defined on the canvas. This makes the use use of i as loop variable a bit safer.

Streamlined Settings dialog

You specify a directory where to start the recursive search for maxima.bat, e.g. the top level directory of your Maxima installation.

The path is saved and displayed relative to your SMath installation directory. You can switch between different Maxima installations on the fly.

SS-3460: Translation of # and empty placeholders

SS-157: Translation of \ in strings

SS-198: Improved default settings for Draw2D/3D regions

These regions now have their x (2D) and x, y axes (3D) scaled by the plot objects, the vertical axis is scaled by the mouse. This can be changed in the Plot settings (double click the region)

These regions are in their initial state after insertion.
