Difference between a<t<b and t>a && t<b
might be because you are supposed to write: *t(i)>=0 && t(i)<pi* NOT: *0>=t(i) && t(i)<pi*

What does the following error mean? Undefined function 'diffjac' for input arguments of type 'function_handle'. Error in Heq_Nwt (line 23) df = diffjac(x1,f,f0)
diffjac.m and dirder.m works perfectly fine for me. Your inputs must be different than intended.
