MATRIX("HOLLOW",order)
- is the order of the Hollow matrix.
is the order of the Hollow matrix.Description
- This function shows the matrix of order 3 with the hollow matrix property.
- A hollow matrix may be a square matrix whose diagonal elements are all equal to zero.
- The real skew-symmetric matrix,adjacency matrix of a finite simple graph and a distance matrix or Euclidean matrix are some examples of Hollow matrix.
- In Calci, users can get different type of hollow matrices.
- For example, to get negative decimal places of hollow matrix is MATRIX("hollow:negative") and to get positive decimal places is MATRIX("hollow:positive").
- Also MATRIX("hollow:negzeropos") is used to get a hollow ineteger matrix with the numbers 0,1 and -1.
- MATRIX("hollow:integer") is used to get any integer numbers of Hollow matrix.
