How the results are stored in a .xlsx file?

1 view (last 30 days)
Hello,
I have the following problem: I want to calculate the RMSE. More specifically I run the algorithm five times and then add the resulting results and divide by five to calculate the average RMSE((RMSE1+RMSE2+RMSE3+RMSE4+RMSE5)/5). I use the command writecell but only the last value of the error is saved the rest is lost. How to save the error every time I run the algorithm ? Below I attach a part of the code.
Your help is important !!!
results = {DA,RMSE};
writecell(results,'results.xlsx')

If you call this code every iteration, writecell will overwrite the file every time, just like you tell it to.

According to me during every iteration the writecell function is overwriting the previous results, that's why you are getting only last value saved. Use the function as shown below to append at the bottom for every iteration,
writecell(results , 'results.xlsx' , 'WriteMode' , 'append');
Look into the documentation for more information.
