Reads the current seed ! ... CALL RANDOM_NUMBER(rSubset(1:n)) ! get random reals 0-1 This works, but I am wondering whether the random numbers generated will be reproduced if I execute this code twice. Since I have not called RANDOM_SEED with a 'PUT' arg, does Fortran selec...
one argument of RANDOM_SEED( ) is size, which is stimulated as follows."must be scalar and of type integer. Set to the number of integers (N) that the processor uses to hold the value of the seed."I tried the example folowed and found N is always equal to 2. If this is the ...
最终得出的结论是异常导致threadLocal.remove()方法没有执行，最后内存泄漏了，以下是本人定位问题的过程。

生成0到1之间随机数值范围 0 <= x < 1，所以不包括1。手册说：CALL RANDOM_SEED()CALL RANDOM_NUMBER (harvest)harvest (Output) Must be of type real. It can be a scalar or an array variable. It is set to contain pseudorandom numbers from the uniform distribution within the range...
! Current generator sets its seed to 1d0 CALL RANDOM_SEED (SIZE = K) ! Sets K = 64 / BIT_SIZE( 0 ) CALL RANDOM_SEED (PUT = SEED (1 : K)) ! Transfer seed to current generator CALL RANDOM_SEED (GET = OLD (1 : K))
call Random_Seed()call Random_Number( a )不需要循环。至于产生随机数与 VB 中的区别，我想应该没有什么区别。既然都是均匀随机数，是不应该有区别的。其实Fortran编译器和VB，应该都是根据系统的一些特征来实现的。例如 GetTickCount 一类的，只是算法可能不同，效果应该是一样的。当然，这取决于具体...
