I applied Lachlan's patch here (http://hg.savannah.gnu.org/hgweb/octave/rev/a1aa52bff079). Closing report.

The trivial patch for bug #45219 also fixes this problem. I'm attaching a changeset.

Confirmed. As a workaround, if you convert both inputs to logical type, then bsxfun works.

This isn't that bad because cliques will still stay as a sparse bool matrix. v is small enough that there probably isn't much point in converting it to a sparse matrix but you could also do "sparse (logical (v))" and bsxfun will still work.

When attempting to use bsxfun to @and a matrix with a vector

cliques = sparse([1,1,2,2],[1,2,2,3],[1,1,1,1],2,5)
v = [1,0,1,0,1]


I get

error: concatenation operator not implemented for '<unknown type>' by 'sparse matrix' operations
