Single precision fixed size matrices

      #include <gandalf/linalg/3matrixf.h>
There is an identical set of functions for handling single precision floating point matrices, the names of which are obtained by replacing "gan_mat34_..." in the above functions with "gan_mat34f_...". For example, to add two single precision $3\times 4$ matrices use
      Gan_Matrix34_f m34A, m34B, m34C;

      /* ... fill m34A and m34B ... */
      gan_mat34f_add_q ( &m34A, &m34B, &m34C );
