Hi all, I am a little perplexed by this warning from matlab: "Not enough input arguments" for my following code. I've looked for documentation to see the problem, but it none of them proved to be helpful to my problem. This warning occured at the line "P = z.p" line 47

"I am a little perplexed by this warning from matlab: "Not enough input arguments" for my following code"
Lets take a look at how you call the function here:
x(1, :) = lsqcurvefit(@(x, e_p) EM_TA_wR1, x0, E_p, delta_Abs(:, 1), lb, ub, optim_lsq);
% ^ zero inputs here
Although you wrote the function EM_TA_wR1 to require three inputs, when you defined that anonymous function you call it with zero inputs. That clearly will not work, you need to call it with all of its required inputs, probably something like this:
@(x, e_p) EM_TA_wR1(x,e_p,z)

Lets try it with your uploaded data.
Note that I also:
  • replaced the very unfortunate IMPORTDATA with the much more reliable, recommended READMATRIX
  • removed duplicate LOAD calls
  • marked unused variables
Now the anonymous function is correctly defined it does not throw an error when it is called. However you have problems due to the fact that your initial conditions lead to lots of NaNs in the objective function output. You will have to debug those.

Hi Stephen, I've made the amendments that you've suggested and now my code could run. Thanks so much!
