Hi,

Here I am pasting a simple code which does a simple integration from - infinity to + infinity:

syms x
C=1;D=1;E=1;N=1;W=1;
alp=1;
z=1;
for P=1:1:20
a=(sqrt(-1))*(C-P);
b=(D-(sqrt(-1))*(P+x));
c=(E+(sqrt(-1))*(N-P));
d=(W^2+x.^2);
e=b*c*d;
f=a/e;
S=alp*(int(f,-inf,inf));
out = vpa(S);
k=double(out)
end

******** The problem is to plot a graph (S Vs P) using all the values of P. Can anyone help me in this regard?

Thanking You!

You have to use: k(P) instead of k

syms x
C=1;D=1;E=1;N=1;W=1;
alp=1;
z=1;
for P=1:1:20
  aa=(sqrt(-1))*(C-P);
  b=(D-(sqrt(-1))*(P+x));
  c=(E+(sqrt(-1))*(N-P));
  d=(W^2+x.^2);
  e=b*c*d;
  f=a/e;
  S=alp*(int(f,-inf,inf));
    out = vpa(S);
    k(P)=double(out)
end
plot(abs(k))
