math - Check existence of solution Matlab -

i have 2 functions return 2 arrays t1 , t2, want calculate h=t1/t2 , if there no solution {do something}. t1 vector , t2 jacobian matrix. (i need solve equation t2*d=t1) try

if isempty(t1\t2)     {doing something} end 

but isempty function returns 0. how can check exestence of solution t1\t2?

in command window matlab says

warning: system inconsistent. solution not exist.  

update: try

d=inv(h)*phi 

it works, difference , how can use command '\'?

you use rank judge if system not have unique solution:

if rank([t2,d]) ~= rank(t2)     {doing something} end
