although this does not matter much, you should add an 'end'
how do you call obj.m with fmincon? and where did you store obj.m??? if you call obj(x0) in the line before your fmincon, does it work then?

Do not use @obj.m -- use @obj

apparently you somewhere call a function "obj.m" with an 'double' input and this is not allowed
we can't help much more if you dont post the line where the error occurred and maybe a summary of the code inside obj.m

sir this is the obj.m program
function f = obj(x)
pm=pi/3;
w=0.008;
wt=10;
ws=0.001;
ka=2;
ku=4;
ta=420;
tu=460;
Lu=60;
La=40;
s=(-(x(2)*(w^(-x(4)))*sin((pi/2)*x(4)))+(x(3)*(w^(x(5)))*sin((pi/2)*x(5))));
r=x(1)+((x(2)*(w^(-x(4)))*cos((pi/2)*x(4)))+(x(3)*(w^(x(5)))*cos((pi/2)*x(5))));
f = 20*log10((ku/sqrt((ta*w)^2+1))*sqrt(r^2+s^2));
sir please do tell me if i have made a mistake.....
