[Help-gsl] Matrix / Vector multiplication

[Peter Jay Salzman]

Just discovered GSL a few hours ago.  Very neat!


I've been trying to figure out how to multiply a vector and matrix.  How is
one supposed to compute something like

   A x

given a gsl_matrix A and a gsl_vector x?   Does x need to be defined as a
nx1 gsl_matrix for a column vector and a 1xn gsl_matrix for a row vector?

Thanks,
Peter
