MATRIXTRACE (a)


  • is any matrix.

Description

  • This function shows the trace value of the given matrix.
  • In  ,   is any matirx.
  • The trace of an nxn square matrix is defined to be the sum of all main diagonal entries.
  • Consider the matrix A with the elements  .
  • Here trace of the matrix A is  = .Where   denotes the entry on the   row and   column of A.
  • Now consider 3x3 matrix  
  • Here tr(A)= a+e+j.

Examples

  1. MATRIXTRACE([[5,19,-36,10,7.6],[20,-17,4.5,43,87]]) = -12
  2. MATRIXTRACE([[10,18,-76,-98],[12,85.4,65,78],[10,15,76,123]]) = 171.4
  3. MATRIXTRACE([[21,54,98,10,17,23],[90,87,65,43,12,10],[13,-543,-987,-154,100,32],[67,87,97,32,11,987]]) = -847
