===========================
I didn't understand,exactly.namely,I have to add a input argument in FSOLVE that include in "i" index values,when call my_function_name?namely I have to write as following?
equ1 = fsolve(@my_function_name , my_guess,i);
========
but I receive following error:
??? Undefined function or variable 'i'.
Error in ==> my_function_name at 51
er = 1w(i)^2;
Error in ==> fsolve at 248
fuser = feval(funfcn{3},x,varargin{:});
Error in ==> my_script at 26
equ1 = fsolve(@my_func_name,my_guess,i);
=============
again,I write total of my code (function and script) as following:
% first : I wrote function section as following:
function output = my_func_name(inputs)
realPartOfInput = inputs(1);
imagPartOfInput = inputs(2);
% k1 , k2 , are known.and w is a vector that length(w)=100.
% namely : w =linspace(1,5,100);
kz = complex(realPartOfInput, imagPartOfInput);
er = 1w(i)^2;
k2 = k1*sqrt(er);
g1 = er*sqrt(kz^2k3^2).*besseli(1,sqrt(kz^2k2^2)).*besselk(0,sqrt(kz^2k3^2))+... sqrt(kz^2k2^2).*besseli(0,sqrt(kz^2k2^2)).*besselk(1,sqrt(kz^2k3^2));
output = [ real(g1); imag(g1)];
% and saved above function in a directory.
% second: I wrote a script that has a "for loop" for different initial guess:
for i =1:100
real_guess(i) = i/100;
imag_guess(i) = i/500;
my_guess = [ real_guess(i) , imag_guess(i)]
equ1 = fsolve(@my_function_name , my_guess);
...
end
% and saved this script same directory with function path.
====================
NOW,how transfer "i" index value in script to "i" index in "1w(i)^2" formula within my function file?
please help me...
