    Quick theory overview:
  • Every set of \(k\) columns in any generator matrix of an MDS code are linearly independent.
  • Every set of \(n-k\) columns in any parity check matrix of an MDS code are linearly independent.

    Procedure:
  • Choose one of the options from the drop-down and click on Submit.
  • The correctness of the chosen option will be displayed in Observations.
  • If the matrix given is a generator matrix of an MDS code proceed to the next example.
  • If the matrix given is not a generator matrix of an MDS code, a message prompting the selection of the linearly dependent columns will be displayed in Observations.
  • Clicking on a column changes its color to yellow indicating that the column has been selected.
  • To deselect a column, click on it again.
  • Select all the linearly dependent columns and click on Submit.
  • The correctness of the answer is displayed in Observations.
  • Next - Displays the next example.
  • Previous - Displays the previous example.
