The objective of this note is to approximate a birth and death matrix B by a close Toeplitz-type one for which explicit formulas for the eigenpairs are known. Numerical evidence of the approximation behavior of the eigenvalues and eigenvectors of B by those of such Toeplitz-type matrices is provided.
