Abstract : A set of matrices is defined, and the complete solution of each matrix is given. The matrices have arbitrary dimension, and a large nuber of parameters. By adjusting these parameters, a matrix of arbitrary dimension can be constructed which has two eigenvectos tht are nearly coincident, which is derogatory (has fewer than the maximum possible number of eigenvectors), or is s nearly singular as desired. Thus a set of matrices is available which forms a convenient set of check matrices for testing computer programs which purport to solve or invert a matrix. The matrices of the set have certain properties of regularity. For selected values of the parameters, the matrices appear as variancecovariance matices in statistics. In particular cases, the eigenvalues (but not the eigenvectors) and the determinants were found. (Autho)
