HyperWork必备知识-templex语言2-函数定义
通过关键字define定义函数，通过关键字include载入文件，而后可以直接调用。当然所定义的函数和调用的代码可以写在一起。外部函数文件，需要保存为eulerXYZ.tpl{'ThistemplexmacrocalculatestheEulerparamsbasedonthreesequentialrotations.}{'RotationsequenceRx->Ry->Rz.}{defineeulerXYZ(rx,ry,rz)}{t1=dtor(rx)}{t2=dtor(ry)}{t3=dtor(rz)}{'Cosinematrix:}{a11=cos(t2)*cos(t3)}{a12=-cos(t2)*sin(t3)}{a13=sin(t2)}{a21=sin(t1)*sin(t2)*cos(t3)+sin(t3)*cos(t1)}{a22=cos(t1)*cos(t3)-sin(t1)*sin(t2)*sin(t3)}{a23=-sin(t1)*cos(t2)}{a31=sin(t1)*sin(t3)-cos(t1)*sin(t2)*cos(t3)}{a32=sin(t1)*cos(t3)+cos(t1)*sin(t2)*sin(t3)}{a33=cos(t1)*cos(t2)}{trace=a11+a22+a33}{'Eulerparameters:}{e0=0.5*sqrt(trace+1.0)}{e1=0.5*sqrt(1.0+2.0*a11-trace)}{e2=0.5*sqrt(1.0+2.0*a22-trace)}{e3=0.5*sqrt(1.0+2.0*a33-trace)}{ife0!=0.0}{e0=sqrt(e0*e0)}{e1=(a32-a23)/(4.0*e0)}{e2=(a13-a31)/(4.0*e0)}{e3=(a21-a12)/(4.0*e0)}{elseife1!=0.0}{e1=sqrt(e1*e1)}{e2=(a13+a31)/(4.0*e1)}{e3=(a21+a12)/(4.0*e1)}{elseife2!=0.0}{e2=sqrt(e2*e2)}{e3=(a32+a23)/(4.0*e2)}{else}{e3=1.0}{endif}{enddefine}调用外部所定义的函数{include"eulerXYZ.tpl"}SYSTEM1JOINTDOF{eulerXYZ(90,0,0)}1FREE{e0}{e1}{e2}{e3}0.50.50.50.00.00.050.00.00.0ENDJOINTDOFENDSYSSYSTEM2JOINTDOF{eulerXYZ(0,90,0)}1FREE{e0}{e1}{e2}{e3}0.50.50.50.00.00.050.00.00.0ENDJOINTDOFENDSYS最终显示SYSTEM1JOINTDOF1FREE0.7071070.707107000.50.50.50.00.00.050.00.00.0ENDJOINTDOFENDSYSSYSTEM2JOINTDOF1FREE0.70710700.70710700.50.50.50.00.00.050.00.00.0ENDJOINTDOFENDSYS函数与调用代码写在一起{definegreeting(first,last)}Dear{first}{last},{enddefine}{greeting("John","Doe")}我们来写一个类似于python的range函数{definerange(start,end,step)}{for(i=start;i<end;i+=step)}{i}{endloop}{enddefine}{range(0,20,2)}来源：TodayCAEer
