maxval
Description
Determines the maximum value of the elements in an array value, or, if the dim argument is supplied, determines the maximum value along each row of the array in the dim direction. If mask is present, only the elements for which mask is .true. are considered. If the array has zero size, or all of the elements of mask are .false., then the result is the most negative number of the type and kind of array if array is numeric, or a string of nulls if array is of character type.
Standard
Fortran 95 and later
Class
Transformational function
Syntax
result = maxval(array, dim [, mask])result = maxval(array [, mask])
Arguments
array- Shall be an array of typeinteger,real, orcharacter.dim- (Optional) Shall be a scalar of typeinteger, with a value between one and the rank ofarray, inclusive. It may not be an optional dummy argument.mask- Shall be an array of typelogical, and conformable witharray.
Return value
If dim is absent, or if array has a rank of one, the result is a scalar. If dim is present, the result is an array with a rank one less than the rank of array, and a size corresponding to the size of array with the dim dimension removed. In all cases, the result is of the same type and kind as array.
