2%CS_LTSOLVE solve a sparse upper triangular system L'*x=b.
3%   x = cs_ltsolve(L,b) computes x = L'\b, L must be lower triangular with a
4%   zero-free diagonal.  b must be a full vector.

6%   Example:
7%       Prob = ssget ('HB/bcsstk01') ; L = cs_chol (Prob.A) ; n = size (L,1) ;
8%       b = rand (n,1) ; x = cs_ltsolve (L,b) ; norm (L'*x-b)
