Correlation in fluid mechanics?

hi, i m working in fluid mechanics. I have done drop size measurements in a spray. To control my spray i have three variable control parameters. I would like to link them to the drop size with a correlation. Is there any function in matlab able to do that? thanks. Jean-Christophe

Yes, you can make a model with the Regression Learner on the Apps tab of the tool ribbon if you have the Statistics and Machine Learning Toolbox. Have your "predictors" (your three variable control parameters) be in a table, and have your ground truth (measured droplet sizes) in a vector. Then start a Regression Learner session. Tell it to use all the available models then pick the one with the lowest MAE or best correlation and Click the Export button to export the model.

Attach your data if you need help with this.
