Good afternoon sir,
Sir I have taken lsqnonlin method to estimate parameters and draw the graphs for prediction.Here i have to draw graphs for 2,3,4 columns but it shows only one column for predictions.sir i request please tell me how to draw graphs for 3rd and 4th columns and also please tell me how to separate graphs.please give me 3 to 5 lines code if possible.
Thanking you sir
the code and graph are
code:
data = [ 1 1 0 0

Before you plot results, we should first make sure that your code is correct - that's why I insist.
At the moment, you subtract the vector Cv(:,2) from each column of the matrix c_data. Thus, lsqnonlin assumes that columns 2, 3 and 4 of your matrix "data" are repetitions of an experiment and that all three columns should be approximated by Cv(:,2) using one set of parameters. But I think this must be wrong since the values for the three columns differ significantly in size.
So again my question: Is it correct that you want lsqnonlin minimize [c_data(:,1)-Cv(:,2);c_data(:,2)-Cv(:,2);c_data(:,3)-Cv(:,2)] simultaneously ?

Thanks for your reply sir.
C = [c_data(:,1)-Cv(:,2);c_data(:,2)-Cv(:,2);c_data(:,3)-Cv(:,2)]
i have tried this sir but i did not get answer.
ERROR:
Arrays have incompatible sizes for this operation.
C=c_data-Cv(:,[2,3,4]);
is it correct sir?. I got only curve fitting for 2nd and 3rd column but i did not get curve fit for 4th column.please tell me how to modify this sir.

Have you looked at nexttile or subplot? These will set up separate axes so that you can draw each curve in its own separate axes.

thanks for your reply sir
i did not see subplot .first i have to fix C = c_data - Cv. but i dont know how to fix sir.

In hindsight, we know that the curves look like a series of Gaussians:
I'm attaching a demo that will fit your data to a specified number of Gaussians.

I'm also attaching a demo that will fit a set of data to a single set of data increasing with exponential growth.
along with a fit I did years ago on COVID when it was just getting started.
