Save a plot from a function in a structure and save the structure
6 views (last 30 days)
I created a function to perform pca calculations and to plot some specific plots, like loadings and scores.
to run this in my scrip i type:
[PCA_Model] = functionPCA(X)
This creates me a structure, where I have variables saved there that I can access using PCA_Model.eigenvalues, PCA_Model.Scores, etc.
Question -> How can I save this structure to access later on, instead of running the script again? Also, the plots I made is there a way to save in the structure like the variables? My objective in a fold of my chosen, I open PCA_Model, and I can see the plots I created plus the variables I saved in the structure

You can save all your workspace data or selected data into an .mat file. Then you can load or simply double click the .mat file to load the data back to the workspace. You can access the data whatever you want. See
For plots, you can also save them in separated files. On your plot, click menu, File, Save or Save As. Then you can re-open the plots by double click or drag-and-drop.
If it does not take too much time to run functionPCA(), I would still recommend calling and running your function every time, instead of saving to various files. Keep your original (source) data. The derived data can always be re-produced.
