50  // <synopsis>
51  // These functions perform element by element logical operations on
52  // optionally masked arrays and/or scalars.
53  // If two arrays are used, the arrays must conform, except for allEQ which
54  // returns False if the arrays do not conform.
55  //
56  // The functions in this file can be divided in 3 groups:
57  // <ul>
58  // <li> Full array operations like ==, near, etc.
59  // They are defined for array-array and array-scalar operations. Arrays
60  // shapes have to be conformant. They operate on all elements
61  // (also the masked ones). The result is an MArray with the same
62  // shape as the input array(s). It will have a mask if one of the
63  // operands has a mask. If both operands have a mask, the resulting
64  // mask is the OR of both masks.
65  // <li> Full reduction functions like ntrue, all, allEQ, etc.
66  // They operate on the unmasked elements only. If there are no unmasked
67  // elements, the results is 0 or True.
68  // <li> Reduction functions working on unmasked elements in parts of the
69  // input array. The result is an MArray that has a mask if the input
70  // array has a mask. An output element is masked off if its input
71  // part has no unmasked elements.
72  // The functors defined at the beginning of this file are used to
73  // operate on each part.
74  // There are 3 flavours:
75  // <ul>
76  // <li> partialXXX reduces one or more axes. E.g. one can count the
77  // number of True elements for particular array axes.
78  // The result is an array with a lower dimensionality.
79  // They can be seen as a special versions of the boxedXXX functions.
80  // <li> slidingXXX operates in a sliding window over the array. So the
81  // result is an array with the same shape as the input, although
82  // the output array is smaller if the edge is not filled.
83  // <li> boxedXXX divides the input array in boxes with the given size
84  // and operates on each box. The result is an array with the same
85  // dimensionality, but with a smaller size.
86  // If the box size does not fit integrally, the edge box is smaller.
