Execution of a logical assignment statement causes evaluation of the logical expression e and assignment of the resulting value to v. If e is a logical expression (rather than an integer between -128 and 127, or a single character constant), then e must have a value of either true or ...
INTEGER:表示整数类型,相当于C#的int数据类型 DOUBLEPRECISION:表示双精度数据类型,相当于C#的double数据类型。 在C#调用Fortran DLL是必须保证参数的一致性,例如在Fortran中变量定义的是REAL类型,而我们传入的是Double,那么就会出现计算错误。 三、编写C#代码调用Fortran DLL ...

Integer m,n Real a(m,n) a=2 End Subroutine sub 只传递地址,维度由定义确定,各维度上下限由其他虚参确定,参数多。 假定大小(Assumed-size) Subroutine sub(a) Real a(*) a(1:6)=1 End Subroutine sub 只传递地址,虚参只能是1维,下线为1,不传递上限,容易越界。
