Exporting data points to Excel with Matlab?

Click For Summary
SUMMARY

The discussion focuses on exporting data points from Matlab to Excel using the xlswrite function. Users are running optimization algorithms with multiple trials and iterations, seeking a method to export the iteration number and best function value to separate sheets in an Excel file. The xlswrite command is confirmed as an effective solution, allowing for bulk writing of data to specified sheets in a single operation.

PREREQUISITES
  • Familiarity with Matlab programming
  • Understanding of optimization algorithms
  • Basic knowledge of Excel file structures
  • Experience with data manipulation in Matlab
NEXT STEPS
  • Research the Matlab xlswrite function documentation
  • Explore Matlab data structures for storing iteration results
  • Learn about optimizing data export processes in Matlab
  • Investigate alternative methods for writing to Excel, such as writetable
USEFUL FOR

Matlab users, data analysts, and researchers involved in optimization tasks who need to export iterative results to Excel for further analysis or reporting.

I have an optimization algorithm running 50 full trials with up to 10,000 iterations each (it breaks off if the error goal is reached before that). I want to export the iteration number and the best function value at each iteration to an excel file, then after each trial completes move to the next sheet and start there with the next trial. Is there a simple way to do it?

Yes. Matlab xlswrite is a very convenient way to write to an Excel file. Matlab can write an entire range of cells to a sheet with one call, so you might be better off saving the data and doing one big write for each sheet.
