HyperWork必备知识-templex语言2-函数定义

2月前浏览1033

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

{' This templex macro calculates the Euler params based on three sequential rotations.}{' Rotation sequence Rx -> Ry -> Rz.}{define eulerXYZ(rx, ry, rz)}{   t1 = dtor(rx)}{   t2 = dtor(ry)}{   t3 = dtor(rz)}{' Cosine matrix:}{   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 }{' Euler parameters:}{   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) }{ if e0 != 0.0 }{   e0 = sqrt(e0*e0) }{   e1 = (a32-a23)/(4.0*e0) }{   e2 = (a13-a31)/(4.0*e0) }{   e3 = (a21-a12)/(4.0*e0) }{ elseif e1 != 0.0 }{   e1 = sqrt(e1*e1) }{   e2 = (a13+a31)/(4.0*e1) }{   e3 = (a21+a12)/(4.0*e1) }{ elseif e2 != 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"}SYSTEM 1 JOINT DOF{eulerXYZ( 90, 0, 0)} 1  FREE  {e0}  {e1}  {e2}  {e3}    0.5  0.5  0.5    0.0  0.0  0.0    50.0  0.0  0.0END JOINT DOFEND SYSSYSTEM 2 JOINT DOF{eulerXYZ( 0, 90, 0)} 1  FREE  {e0}  {e1}  {e2}  {e3}    0.5  0.5  0.5    0.0  0.0  0.0    50.0  0.0  0.0END JOINT DOFEND SYS

最终显示

SYSTEM 1 JOINT DOF  1  FREE  0.707107  0.707107  0  0    0.5  0.5  0.5    0.0  0.0  0.0    50.0  0.0  0.0END JOINT DOFEND SYSSYSTEM 2 JOINT DOF  1  FREE  0.707107  0  0.707107  0    0.5  0.5  0.5    0.0  0.0  0.0    50.0  0.0  0.0END JOINT DOFEND SYS

函数与调用代码写在一起

{define greeting(first, last)}Dear {first} {last},{enddefine}{greeting("John", "Doe")}

我们来写一个类似于python的range函数

{define range(start, end, step)}  {for (i = start; i < end; i += step)}    {i}  {endloop}{enddefine}{range(0, 20, 2)}
