Sorry for this bad mixing between an unworkable line and its workaround.
Dropping sign() on the first line is OK for a copy/past:
> A  =  sprand(839,172,2/172,  "normal");
> i  =  A>0;  A(i)  =  1;
> i  =  A<0;  A(i)  =  -1;
> p  =  rand(172,1);
> tic()
> for  i  =  1:1000
>      M1_v  =  A*p;
> end
> toc()
