integration error

I am trying to use integration with MATALB. initially it was showing error as Conversion to double from sym is not possible

here is my code.. please assist

a=3.6;

N0=-174;

fq=3.5*10^9;

c=3*10^8;

R=100;

G0= (c/(4*pi*fq))^2;

P=1;

Te= abs((P*G0)/(N0*(R^a)));

syms x;

t=(.1:.1:.5);

for p=.1:.1:.5

S=abs(((x-sqrt(3))^-a )+((x+sqrt(3))^-a )+ 2*(((x-sqrt(3/2))^2 + (9/4)))^(-a/2)+ 2*(((x+sqrt(3/2))^2 + (9/4)))^(-a/2))

k=1+(Te*S);

f1=(x*log2(1+(Te/x^a*(k))));

q=(int(f1,0,1));

f2=x*t*log2(1+ (Te/x^a));

w=(int(f2,0,1));

f3=x*(1-t)*log2(1+ (Te/x^a));

e=(int(f3,0,1));

C= 20*pi*10^6*(q+(w/3)+(e/3));

plot(t,double(C));

hold on ;

grid on ;

end

I am not getting any graph though the error is gone after I used plot(t,double(C));

Please format your code as explained in the "Markup help" link on this page.

This is not the same code as you emailed to me, and when you emailed me you did not indicate what problem you had observed. Unless I was supposed to guess which program had generated that AutoSave (.asv) file and figure out how to restore it to see an error message?

[Ashesh]

this is the actual code..I have made some changes into it after reading several threads over here. but still the execution is taking too much time and the graph is not what I was expecting.
