Wrong documentation for *trmv in the BLAS module

Wrong documentation for *trmv in the BLAS module

[Fabian Jakobs]

Hello,

The documentation for the functions strmv, dtrmv, ctrmv and ztrmv in the BLAS 
module seems to be wrong. This is taken from the HTML documentation:

>Function: int gsl_blas_strmv (CBLAS_UPLO_t Uplo, CBLAS_TRANSPOSE_t TransA, 
>CBLAS_DIAG_t Diag, const gsl_matrix_float * A, gsl_vector_float * x)
...
>These functions compute the matrix-vector product and sum y =\alpha op(A) x + 
>\beta y for the triangular matrix A, where op(A) = A, A^T, A^H for TransA = 
>CblasNoTrans, CblasTrans, CblasConjTrans. When Uplo is CblasUpper then the 
>upper triangle of A is used, and when Uplo is CblasLower then the lower 
>triangle of A is used. If Diag is CblasNonUnit then the diagonal of the 
>matrix is used, but if Diag is CblasUnit then the diagonal elements of the 
>matrix A are taken as unity and are not referenced. 

The part "sum y =\alpha op(A) x + \beta y" doesn't make sense since theese 
functions don't have y, alpha or beta as argument. it should be "x = op(A) x"

Thanks for the bug report. I'll take a look at that.
