Each global vector will have 5 elements with corresponding values as ordered above.The state functions and user defined functions for this example can be expressed in the Symbolic language of STRUREL as shown below. // 1. Use vector input in C/C++ source file FLIM(1){Stone: Circular cross section} = FUNC(1)DEFFUNC(1,CPP,CppStone,\_Circular.cpp\// 2. Use global names in C++ source file FLIM(2){Stone: Circular cross section} = FUNC(2)DEFFUNC(2,CPP,CppStone,\_Circular.cpp\// 3. Use explicit arguments in C++ source fileFLIM(3){Stone: Circular cross section} = FUNC(3)(Load,Strength,Diameter,PAR1,PAR2,PI)DEFFUNC(3,CPP,CppStone,\_Circular.cpp\6. C/C++ source fileThe C/C++ source file must contain at least one double export function prepared by rules described above. In our example three export functions need to be defined in source file %u2018Stone_Circular.cpp%u2019 for processing by selected compiler. The first we need to provide all required definitions for binding with STRUREL placed in an include file %u2018strurel.h%u2019.
