Le forum de XCAS

Hello

xCas has set operation commands, for a future version please add a submenu 'SET' in the PC version, however the following command is very important in set theory

cartesian_product( set[1], set[a,b] ) [enter] => A X B= {(1,a),(1,b)}

this is to expand the functionality of cartesian_product if the two arguments are sets

Thank you very much

cartesian_product is not a set theory command.
You can run * to make the product of two sets.

Hello

but some CAS (MAXIMA) include it within the list of set instructions, it is important to have an alias to '*' as an explicit name, I think it costs nothing to extend the functionality of this command, as well as including the complement of a set command, and creating a submenu of set commands and similar in the PC version.
