Parameters

in

uplo

uplo='U': upper triangular. uplo='L': lower triangular.

Returns:

An integer. If the returned value <0, then the input is not a character indicating an upper- or lower-triangular matrix. Otherwise the constant value corresponding to uplo is returned: 121 (BLAS_UPPER) for uplo='U', 122 (BLAS_LOWER) for uplo='L'.
