In Fortran, arrays can be multidimensional. To find the minimum value along aspecific dimension, we need to specify the `dim` argument. For instance, consider a two-dimensional array `B`: fortran real :: B(2, 3) = reshape([1.0, 4.0, 3.0, 2.0, 7.0, 5.0], [2, 3]) If we want ...

Certain function and subroutine names3 are defined as part of the FORTRAN language; there are 115 in all. These perform such commonly required tasks as returning the absolute value of a number, ABS (x), or establishing whether a pointer is associated, ASSOCIATED (ptr). A full list of the...

我发现这篇关于MINVAL和MINLOC的讨论 Finding [index of] the minimal value in array which satisfies a condition inFortran我想知道对于有多个最小值/最大值的情况,MINLOC和MAXLOC是否能够返回一个数组。 另外,一旦我获得了索引数组,我如何才能最好地遍历这些索引?
