> If yes, can someone send me a small code snippet that would achieve the same. matrix->block is the memory block that stores the values matrix->owner is an integer that indicates whether the block should be freed with the matrix gsl_matrix * A = gsl_matrix_alloc(1,1); gsl_matrix * B = gsl_matrix_alloc(9,9); assert(A->owner); assert(B->owner); gsl_block_free(A->block); //free A's memory block without freeing A A->block = B->block; //A takes ownership of B's block A->data = B->data; //A points into B's block B->owner = 0; //B is relieved of ownership gsl_matrix_free(B); //B is free'd, but his block isn't -- James Bergstra http://www-etud.iro.umontreal.ca/~bergstrj _______________________________________________ Help-gsl mailing list [email protected] http://lists.gnu.org/mailman/listinfo/help-gsl
