How do I make a matrix in a specific for loop?
显示 更早的评论
I am using a for loop with the function "fminsearch" and want to save the data into a matrix, with each iteration of the for loop saving to the subsequent cell, rather than replacing the variable name with each iteration.
Here is the code that I have:
options = optimset();
for i=1:7
best_fit_eff(i) = fminsearch(@curvefit, [1,1], options, dose, D_eff(:,i));
end
And I get an error displaying "In an assignment A(I) = B, the number of elements in B and I must be the same."
If it take out the (i) after best_fit_eff, it would run properly, but then Matlab would only retain the best fit of the 7th iteration, but I want a matrix with the best fit values of all the iterations. Can anyone help me please?

I have actually had this very question not too long ago. What you have to do here is create another variable in the for loop and store the value of best_fit_eff into the array after every iteration. Here is code that you could possibly use to get around this problem. Also, it looks like your best_fit_eff outputs a vector with two values rater than one, so in the code below, I assigned the first value to a variable called "param1" and the second value to "param2". This should work without any errors. Let me know if it doesn't!
options = optimset();
for i=1:7
best_fit_eff = fminsearch(@curvefit,[1,1], options, dose, D_eff(:,i));
param1(i) = best_fit_eff(1);
param2(i) = best_fit_eff(2);
end
