intgration for fi (as part of The Invert Fourier transform

1 view (last 30 days)
v*=C(1)+C(2)*x+C(3)*x^2+C(4)*x^3
C_orginal =[ 0;
-(M0*l*exp(2*fi*i))/(EI*(8*exp(fi*i) + 2*exp(2*fi*i) + 2));
(M0*exp(fi*i)*(2*exp(fi*i) + 1))/(EI*(8*exp(fi*i) + 2*exp(2*fi*i) + 2));
-(M0*exp(fi*i)*(exp(fi*i) + 1))/(2*EI*l*(4*exp(fi*i) + exp(2*fi*i) + 1))];
I re-arranged the vector and turned it from symbolic to numeric
i=i
M_0=1
EI=1
L=100
x=0.5*L
N=20
---
for k=-N:N
fi=-pi:pi/900:pi;
C5=M_0/(2*EI);
gama=exp(i*fi);
delta_0=4+2*cos(fi);
C_2= [0 ;
-C5*L*gama/delta_0;
C5*(2*gama+1)/delta_0;
-C5*(gama+1)/(L*delta_0)];
V_befor_int=(x*C_2(2)+(x^2)*C_2(3)+(x^3)*C_2(4))*exp(i*fi*(-k));
V_K_ORIGINAL(k+N+1)=(1/(2*pi))*trapz(fi,real(V_befor_int)); (<__the problam is here)
end;
I get Unreasonable resolt for the integral for fi on the equation :V_K_ORIGINAL
how can i do the interation??
please, see the attached image
tnx for your help
