With the standard input grammar, the precedence of ‘-’ as a prefix
behaves strangely. a^-b*c becomes a^(-b*c) while
a^b*c ⇒ (a^b)*c.
Using divide to divide a polynomial by an integer does not work.
The command example executes the example it gives. This can lead
to unpredictable results if the variables and constants in the example
have already been given values by the user.
The function minor should be modified to accept lists for
row and col.
Resultant might be modified to compute the resultant of a system of polynomials with respect to a list of variables.
Things that are labeled as Operators can occur in expressions output by
Jacal. Things that are labeled as Commands act upon their arguments and
do not generally occur in expressions output by Jacal. Things that are
labeled as flags are set to control aspects of the Jacal
environment.
The examples throughout this text were produced using SCM.
Jacal has several input grammars it understands. The standard
grammar (which is the same as the std and disp2d
grammars) is used in this manual. It is very similar to Maxima
input grammar and the Algol family of computer languages.
