How to concatenate output of objective function for lsqcurvefit?
조회 수: 6(최근 30일)
I have an objective function of the form
function [I_num] = PSw_EK_v7(k_m, s_bulk)
k_m is the variable I want to optimize while s_bulk is an array of input data which I want to feed the input function. I am using the lsqcurvefit/lsqnonlin function to fit my simulation to experimental data of the form.
s_bulk = [0, 5e-06, 10e-06, 20e-06, 50e-06, 100e-06];
I_exp = [0, 2.35e-03, 2.7e-03, 3.125e-03, 3.29e-03, 3.25e-03]
Now what I am trying to do is feed the lsqcurvefit function my s_bulk array and get an array of I_num values but I am having difficulty doing that. I have tried arrayfun function but that does not seem to work inside the lsqcurvefit function.
So, to put things short I want to give my s_bulk array and get an array of I_num because that is what lsqcurvefit expects.
[k_m,resnorm,residual,exitflag,output]=lsqcurvefit(@PSw_EK_v7, k_m_0, s_bulk, I_exp, lb, ub, options);
