Hi,
I am working on the 1.15 version of GSL and get a wrong result in vector v
from gsl_vector_alloc_col_from_matrix. (matrix/gsl_vector_double.h,
matrix/getset_source.c)
My understanding is that it should return the matrix column data for a
specified column. So, with gsl_vector_alloc_row_from_matrix, here the
specified row will be returned.
Example:
Matrix:
1 1 1 1 1 1 1
2 2 2 2 2 2 2
3 3 3 3 3 3 3
4 4 4 4 4 4 4
Expected result for column offset 4 with vector size 4 (specified by no. of
matrix rows): 1 2 3 4
x x x x 1 x x
x x x x 2 x x
x x x x 3 x x
x x x x 4 x x
Actual result:
x x x x 1 1 1
2 x x x x x x
x x x x x x x
x x x x x x x
I can not reproduce this. It would help if you please could post your
code, output, and expected output.
Cheers,
Peter
