The value of MINVAL ((/2, 3, 4/)) is 2 because that is the minimum value in the rank-one array.
The value of MINVAL (B, MASK=B .GT. 0.0) finds the minimum value of the positive elements
of B.

C is the array .

MINVAL (C, DIM=1) has the value (2, 3, 4). 2 is the minimum value in column 1; 3 is the
minimum value in column 2; and so forth.
MINVAL (C, DIM=2) has the value (2, 5). 2 is the minimum value in row 1 and 5 is the minimum
value in row 2.
MM_PREFETCH
The following rules apply if dim is specified:
• The array result has a rank that is one less than array, and shape (d 1 , d 2 , ...,
d DIM–1 , d DIM+1 , ..., d n ), where (d 1 , d 2 , ..., d n ) is the shape of array.
• If array has rank one, MINVAL (array, dim [,mask]) has a value equal to
that of MINVAL (array [,MASK = mask]). Otherwise, the value of element
(s 1 , s 2 , ..., s DIM–1 , s DIM+1 , ..., s n ) of MINVAL (array, dim [,mask]) is equal
to MINVAL (array (s 1 , s 2 , ..., s DIM–1 , :, s DIM+1 , ..., s n ) [,MASK = mask (s 1 ,
s 2 , ..., s DIM–1 , :, s DIM+1 , ..., s n )]).
If array has size zero or if there are no true elements in mask, the result (if dim
is omitted), or each element in the result array (if dim is specified), has the
value of the positive number of the largest magnitude supported by the
processor for numbers of the type and kind parameters of array.

Arguments:
address
hint (opt)
Prefetches data from the specified address on one memory cache line.
CALL MM_PREFETCH (address [, hint] [, fault] [, exclusive])
Subroutine
Is the name of a scalar or array; it can be of any type or rank. It specifies the
address of the data on the cache line to prefetch.
Is an optional default integer constant with one of the following values:
