EigenCalc is a simple app that computes the eigenvalues and eigenvectors of a given matrix. It is perfect for student that study Linear Algebra or Matrices. You can set the matrix dimensions using the scrollbars and then you can input the matrix elements by typing in each cell (the cells become active/inactive once you move the respective scrollbar). You can move to another cell either by pressing the NEXT key on the soft keyboard, or by tapping the desired cell. If you leave a cell empty the app assumes that the respective value is equal to zero. After you have entered the entries of the desired matrix, you can press one of the available buttons to perform an operation on the given matrix. Besides eigenvalue and eigenvector computation you can also compute the characteristic polynomial, perform Gauss Jordan elimination or Gram Schmidt orthogonalization.
