plotting help with loop and complex matrix

i am trying to save values from the 50th slice of matrix of 101 (one value to the left of the center), which is spit out by this 'pfield' program, and graph them with the variable i have listed as 'imp"

im just having trouble figuring out how to save only the one value, curr and the 'imp' from each loop so i can plot the relation at the end

the program 'pfield' works prefectly, so i'm not worried about that, just trying to get the variable 'cur' on one axis and 'imp' on the othe

(the matrix pfield spits out is complex, thats why there is 'abs' in there)

close all

clc

addpath c:\antennas\ewa;

l=.68;

a=(.00002);

ker='a';

basis='d';

E=[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,100000,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]

x=(0:1:100);

for a=.00002:.00001:.01

pfield(l,a,E,ker,basis);

cur=abs(ans(50))

imp=100/cur

plot(imp,cur);

hold on

end

hold off

Store the output of the function pfield in a variable and use it. You can try changing your for loop code as follows:

cur = [];
for a=.00002:.00001:.01
curOut = pfield(l,a,E,ker,basis);
cur = [cur abs(curOut(50))];
end
imp = 100./cur;
plot(imp,cur);

Refer to the documentation of function.

this worked, thank you
