I want to send output values from MATLAB to an Excel file

I have added an example Excel file and the Matlab file from which the data is to be taken. For Background: I have multiple .mat files with a signal that I vary with 2 variables 1. Target position/t(in the matlab code) and 2. Gain values(again in the matlab code). For example when the .mat file opened by the matlab code reads"Newexp0.75Gain_0.5Target.mat", The target is at 0.5 and gain value is 0.75. I have .mat files ranging from 0.5 to 2.1 Target position/t with increment of 0.1. The gain value ranges from 0.5 to 0.8 with increment of 0.5.
The different outputs as you'll see in the excel file attached, that I want in an excel file are Amplitude, Error, Period, Frequency.
Is there any better way to do this? As it is taking a very long time totabulate them manually in excel

FreqFinal = mean(freq)
PeriodFinal = mean(period)
error = midline-t
amplitudeFinal= mean(max(y)-midline)
Data_export = [FreqFinal PeriodFinal error amplitudeFinal]
writematrix(Data_export,'Filename.xlsx','Delimiter','tab') % check with writematrix

The "Delimiter" option is not valid for Excel files (because they are not text files and do not use delimiters).
You can see that the "Delimiter" option is listed under the section "Text Files Only":

Thank you! I removed demlimiter and space and just gave it a range so it worked.
Data_export = [FreqFinal PeriodFinal amplitudeFinal error]
writematrix(Data_export,'ExampleMatlab.xlsx','Range','CD9')

data = [1 2 3; 4 5 6; 7 8 9]; % create some data to write to the file
% write the data to an Excel file named "myfile.xls"
xlswrite('myfile.xls', data);
