Detailed Description

the C interface for minmax

Returns the minimum and the maximum value along a given dimension
or for all of the elements of an array.

float ha[] = {1, 2, 3, 4, 5, 6};
array in = array(2, 3, ha);
array minvals, maxvals;

minmax(minvals, maxvals, in, 0);
print(minvals);
print(maxvals);
// minvals = 1.0000    3.0000    5.0000
// maxvals = 2.0000    4.0000    6.0000

minmax(minvals, maxvals, in, 1);
print(minvals);
print(maxvals);
// minvals = 1.0000
//           2.0000
//
// maxvals = 5.0000
//           6.0000
