Checks to see if each element in the two matrices are equal: aij == bij
NOTE: If any of the ele
Checks to see if the matrix is positive semidefinite:
xT A x >= 0
for all x where x is a non-zero
Checks to see if it is a square matrix. A square matrix has the same number of
rows and columns.
Checks to see if any element in the matrix is NaN.
Checks to see if any element in the matrix is NaN of Infinite.
Checks to see if each corresponding element in the two matrices are within
tolerance of each other
Checks to see if the matrix is a vector or not.
Checks to see if every value in the matrix is the specified value.
Checks to see if all the diagonal elements in the matrix are positive.
Checks to see if a matrix is orthogonal or isometric.
Returns true if the matrix is symmetric within the tolerance. Only square
matrices can be symmetric
Checks to see if a matrix is upper triangular or Hessenberg. A Hessenberg
matrix of degree N has th
