## Function/Subroutine Documentation

### subroutine slatb4 (character*3 path, integer imat, integer m, integer n, character type, integer kl, integer ku, real anorm, integer mode, real cndnum, character dist)

SLATB4

Purpose:

``` SLATB4 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.```

M

```          M is INTEGER
The number of rows in the matrix to be generated.```

N

```          N is INTEGER
The number of 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.```
