integration error while converting a variable from syms to double

Hi, I am trying to use integration with MATLAB but its showing some typical errors. please assist

error:

??? Error using ==> reshape
To RESHAPE the number of elements must not change.

Error in ==> sym.maple at 94
      result = reshape(result,size(varargin{3}));

Error in ==> sym.int at 51
   r = reshape(maple('map','int',f(:),[x.s '=(' a.s ')..(' b.s ')']),size(f));

Error in ==> capacity2 at 24

my code

     close all;
     clear all;

      a=3.6;
      N0=-174;
      f=3.5*10^9;
      c=3*10^8;
      R=100;
      G0= (c/(4*pi*f))^2;
      P=1;
      Te= (P*G0)/(N0*(R^a));
      p=.1:.1:1;

      syms x;

      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));

      f1=x/log2(1+(Te/((x^a)*(1+(Te*S)))));
      a1=int(f1,x,0,p);

      f2=(4*x)/log2(1+(Te/x^a));
      b1=int(f2,x,p,1);

      I=a1+b1; 

      C=(20*10^6)/(2*pi*I);

      plot(t,double(C));
      hold on ;
      grid on;

thanks
