% Note :- in this code y & x has 10 values, but every time I run % the command it will give me this error... %*(??? Operands to the and && operators must be convertible to logical scalar values.)*
Error in ==> dewpointT at 75 if (abs(raw(1)) < 1e-5 && abs((y./K)-x) < 1e-5)
raw(1)= sum(y./K)-1;
if (abs(raw(1)) < 1e-5 && abs((y./K)-x) < 1e-5)
break

Hi,
if y and x are vectors, then abs((y./K)-x)<1e-5) is a (logical) vector as well. You will need to decide, if the relation must hold for at least one index, or for all of them. Replace by
any(abs((y./K)-x)<1e-5))
or
all(abs((y./K)-x)<1e-5) )
accordingly.

The error message is very clear: "Operands to and && operators must be convertible to logical scalar values." It is always worth to read the error messages of Matlab.

Nasir, it doesn't bomb out with an error if you change to &, but that doesn't mean that it works. Please review Titus's response and study the documentation for "any" and "all"
