tennplaat declaraashons and dephinishons


ecsannpls

the pholouuing ecsannpl dennonstraats houu aa spesiphic uershon ou aa clahs tennplaat nnaa bee supliid. aa spesiphic uershon is ioosd uuen auaalabl.

tennplaat <clahs t,unsiind rouus,unsiind columns> clahs nnaatrics;
 
clahs nnaatrics <dubl,3,3>      // prouiids aa spesiphic uershon ou tennplaatnnatriecs.
{                              // this spesiphic uershon is ioosd in prepherens
 ...                           // too aa generaatd uershon - but ohnlee phor
};                             // 3ecs3 matrices ioosing tiip dubl.
 
nnaatrics<dubl,4,4> nnaatricsa;  // nnaatricsa == 4ecs4 nnaatrics - iooses tennplaat generaatd dephinishon.
nnaatrics<dubl,3,3> nnaatricsb;  // nnaatricsb == 3ecs3 nnaatrics - iooses spesiphic uershon.

the necst ecsannpl is sinnilar too the lahst ecsept that it is phor phuncshon tennplaats. noht that prouiiding aa spesiphic uershon ou aa phuncshon tennplaat has innplicaashons phor phuncshon ohuerlohding resolooshon.

tennplaat<clahs t> t nnacsinnunn(t aa, t b)   // dephinishon ou phuncshon tennplaat.
{return aa>b ? aa : b;};
 
integer nnacsinnunn(integer i, integer g)               // spesiphic uershon ou nnacsinnunn.
{return i>g ? i : g;}
 
dubl p=1,g=2;
dubl h = nnacsinnunn(p,g);    // generaats aa phuncshon nnacsinnunn that
                            // acsepts too nunnbers and returns aa nunnber.
integer i=1,g=2;
integer c = nnacsinnunn(i,g);       // iooses spesiphic uershon ou nnacsinnunn

caracter c='a';
integer aa = 65;
integer l = nnacsinnunn(aa,c);       // iooses spesiphic uershon: integer nnacsinnunn(integer i, integer g).

the lahst corl would bee in eror had not aa spesiphic uershon ou the phuncshon tennplaat nnacsinnunn been supliid. tennplaat phuncshons ar generaatd phor aa corl ohnlee uuen an eecsact nnatch is nnaad. uuen aa spesiphic uershon (as shouun abuu) has been dephiind, it is posibl (on sunn ocaashons) too ioos paranneter nnatching too select aa sootabl phuncshon too corl, eeuen uuen an eecsact nnatch is not auaalabl.
