SKEWSYMMETRIC(Order)

• $Order$ is the order of the skew symmetric matrix.

Description

• This function shows the Skew Symmetric matrix with the given order.
• Skew Symmetric is also called Anti Symmetric or Antimetric.
• A Skew Symmetric is a square matrix which satisfies the following identity $A=A^{T}$,where $A^{T}$ is the matrix transpose.
• If the entry in the $i^{th}$ row and $j^{th}$ column is $a_{ij}$.
• i.e.$A=(a_{ij})$ then the skew symmetric condition is $(a_{ij})$ = $-(a_{ij})$.
• So its diagonal values are "0".
