pol­expr – A parser for poly­no­mial ex­pres­sions

The pack­age pro­vides \poldef: a parser for poly­no­mial ex­pres­sions based upon the \xint­d­ef­func mech­a­nism of the pack­age xin­t­expr.

The parsed ex­pres­sions use the op­er­a­tions of al­ge­bra (in­clu­sive of com­po­si­tion of func­tions) with stan­dard op­er­a­tors, frac­tional num­bers (pos­si­bly in sci­en­tific no­ta­tion) and pre­vi­ously de­fined poly­no­mial func­tions or other con­structs as rec­og­nized by the \xin­t­expr nu­mer­i­cal parser.

The poly­no­mi­als are then not only gen­uine \xin­t­expr nu­mer­i­cal func­tions but ad­di­tion­ally are also known to the pack­age via their co­ef­fi­cients. This al­lows ded­i­cated macros to im­ple­ment poly­no­mial al­go­rith­mics.
