math­tools – Math­e­mat­i­cal tools to use with ams­math

Math­tools is part of the mh bun­dle, which pro­vides a se­ries of pack­ages de­signed to en­hance the ap­pear­ance of doc­u­ments con­tain­ing a lot of math­e­mat­ics. The main back­bone is ams­math, so those un­fa­mil­iar with this re­quired part of the LaTeX sys­tem will prob­a­bly not find the pack­ages very use­ful.
Math­tools pro­vides many use­ful tools for math­e­mat­i­cal type­set­ting. It is based on ams­math and fixes var­i­ous de­fi­cien­cies of ams­math and stan­dard LaTeX. It pro­vides:
– Ex­ten­si­ble sym­bols, such as brack­ets, ar­rows, har­poons, etc.; – Var­i­ous sym­bols such as \coloneqq (:=); – Easy cre­ation of new tag forms; – Show­ing equa­tion num­bers only for ref­er­enced equa­tions; – Ex­ten­si­ble ar­rows, har­poons and hookar­rows; – Starred ver­sions of the ams­math ma­trix en­vi­ron­ments for spec­i­fy­ing the col­umn align­ment; – More build­ing blocks: mult­lined, cases-like en­vi­ron­ments, new gath­ered en­vi­ron­ments; – Maths ver­sions of \make­box, \llap, \rlap etc.; – Cramped math styles; and more...
