WebFeb 2, 2024 · Courses. Practice. Video. A tridiagonal matrix is a matrix that has non-zero elements only at the main diagonal, diagonal below and above it. All other elements are zero. For this reason tridiagonal matrices of dimension smaller than or equal to 3 seem meaningless. Example 1: [a11, a22, 0 , 0 , 0 , 0 ] [a21, a22, a23, 0 , 0 , 0 ] Webjax.scipy.linalg #.
