#include <flint/gr_mat.h>GR_MAT_TMP_INIT_SHALLOW_TRANSPOSE(AT, A, ctx)sourceGR_MAT_SHALLOW_TRANSPOSE(AT, A, ctx)sourceGR_MAT_TMP_CLEAR_SHALLOW_TRANSPOSE(AT, ctx)sourceGR_MAT_TMP_INIT_SHALLOW_TRANSPOSE makes AT a temporary transpose of A whose entries are shallow copies (sharing heap data) of those of A, allocated on the stack when small. It can be read like a window, and written to provided that the changes are copied back with GR_MAT_SHALLOW_TRANSPOSE(A, AT, ctx), which copies the transpose of its second argument shallowly into its first (the two must not be aliased). GR_MAT_TMP_CLEAR_SHALLOW_TRANSPOSE frees the temporary without clearing the shared entries. The classical multiplication uses this to turn the columns of the right factor into contiguous vectors for dot products.
