Remarks

Zero matrix elements are not stored, so assigning a non-zero value to a matrix element outside the bandwidth of the matrix raises an exception.

Exception	Condition
CenterSpace.NMath.Matrix..::.NonModifiableElementException	Thrown when an attempt is made to assign a non-zero value to a matrix element that is outside the matrix bandwidth.
