## Synopsis

### Functions/Subroutines

subroutine **clatb5** (path, imat, n, type, kl, ku, anorm, mode, cndnum, dist)**CLATB5**

## Function/Subroutine Documentation

### subroutine clatb5 (character*3 path, integer imat, integer n, character type, integer kl, integer ku, real anorm, integer mode, real cndnum, character dist)

**CLATB5**

**Purpose:**

CLATB5 sets parameters for the matrix generator based on the type of matrix to be generated.

**Parameters***PATH*PATH is CHARACTER*3 The LAPACK path name.

*IMAT*IMAT is INTEGER An integer key describing which matrix to generate for this path.

*N*N is INTEGER The number of rows and columns in the matrix to be generated.

*TYPE*TYPE is CHARACTER*1 The type of the matrix to be generated: = 'S': symmetric matrix = 'P': symmetric positive (semi)definite matrix = 'N': nonsymmetric matrix

*KL*KL is INTEGER The lower band width of the matrix to be generated.

*KU*KU is INTEGER The upper band width of the matrix to be generated.

*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.

*MODE*MODE is INTEGER A key indicating how to choose the vector of eigenvalues.

*CNDNUM*CNDNUM is REAL The desired condition number.

*DIST*DIST is CHARACTER*1 The type of distribution to be used by the random number generator.
