Can you elaborate your concern.As far as I understand your GUI has one pushbutton and a pop menu with 10 options. What exactly do you want to do when a push button is clicked?

Hi,
You can read a column from a ‘.csv file’ using readmatrixfunction in MATLAB. Refer to this documentation link for more detail:
https://www.mathworks.com/help/matlab/ref/readmatrix.html
For Example, this code reads the 1st column of data with 4 rows
readmatrix('csvfilename.csv','Range',[1,1,4,1]);
You can add the code in ValueChangedFcn Callback of Pop-up menu.
