RE: autoconf usage : -DHAVE_GSL ?

Dear Brian,
For the wrapper classes that I am preparing (so far, complex, permutations,
vector & matrices) I would like to have the last version of GSL with your
last additions (LU and LU inverse for a complex matrix, etc). I am working
chiefly in Windows, this days. Would it be possible for you to create
another setup.exe with an updated version, some time?

Concerning matrices. There is a typo in the documentation, pag 84, it should
say gsl_matrix_mul_element (and gsl_matrix_div_element) instead of
gsl_matrix_mul, which is very misleading (unless you read carefully the
title makes you believe it's the product of two matrices not the product of
the elements).

Actually, you do not include the product of two matrices as matrix operation
but in linear algebra. Why? The product of two matrices is guaranteed to
exist, e.g, the matrix are a ring, so the operation is well defined. In the
same grounds that you include the addition of two matrices (matrices are a
group) I would tend to add the product.

Best,
jj

how about,

AC_SEARCH_LIBS(sin, m);
AC_SEARCH_LIBS(cblas_daxpy,gslcblas)
AC_SEARCH_LIBS(gsl_version,gsl)
