Is there a nice way to obtain the jacobian of a system of ODEs ? For example with
I can't seem to find an easy way to do it, other than re-write the system altogether
s_y:=x + a*y:
.....which seems horrible.
I see it is very easy to define a simple function in Maple using ->
But what if more than a single expression is needed and if local variables are needed ? Is there a way to put several statements and use local variables in a function definition ? For example to define a function that takes a list as it's argument and returns the arithmetic mean or the simple sum. Must such things be done with a procedure ?
which seems to work OK.
However, this generates an error
Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct
Plotting error, empty plot
...as does any other range I have tried. I guess it's something very simple, but if someone can point me in the right direction I would appreciate it !
I'm very new to maple and I've been experiencing a few difficulties. One in particular is quite frustrating: when opening a worksheet in classic worksheet mode I get a message that it was created in an earlier version, and after clicking OK maple crashes. For example, with the document here:
I am using Maple 12.
This problem does not occur in standard gui mode, only classic worksheet mode but for a variety of reasons I wish to use classic as much as possible.
