CLATB4
CLATB4 sets parameters for the matrix generator based on the type of matrix to be generated.
[in] | PATH | PATH is CHARACTER*3 The LAPACK path name. |
[in] | IMAT | IMAT is INTEGER An integer key describing which matrix to generate for this path. |
[in] | M | M is INTEGER The number of rows in the matrix to be generated. |
[in] | N | N is INTEGER The number of columns in the matrix to be generated. |
[out] | TYPE | TYPE is CHARACTER*1 The type of the matrix to be generated: = 'S': symmetric matrix = 'H': Hermitian matrix = 'P': Hermitian positive (semi)definite matrix = 'N': nonsymmetric matrix |
[out] | KL | KL is INTEGER The lower band width of the matrix to be generated. |
[out] | KU | KU is INTEGER The upper band width of the matrix to be generated. |
[out] | ANORM | ANORM is REAL The desired norm of the matrix to be generated. The diagonal matrix of singular values or eigenvalues is scaled by this value. |
[out] | MODE | MODE is INTEGER A key indicating how to choose the vector of eigenvalues. |
[out] | CNDNUM | CNDNUM is REAL The desired condition number. |
[out] | DIST | DIST is CHARACTER*1 The type of distribution to be used by the random number generator. |
