OUTPUT: True if the matrix is square and equal to the negative of its conjugate transpose, and False otherwise. Note that if conjugation has no effect on elements of the base ring (such as for integers), then the is_skew_symmetric() method is equivalent and faster.

For example, with a 3-D array the elements in the third dimension of the array are commonly called pages because they stack on top of each other like pages in a book. Each page is a matrix that gets operated on by the function.

The complex conjugate transpose of a matrix interchanges the row and column index for each element, reflecting the elements across the main diagonal. The operation also negates the imaginary part of any complex numbers. For example, if B = A' and A (1,2) is 1+1i , then the element B (2,1) is 1-1i.
