I am trying to read in a data file into MATLAB, but it is not working correctly. My code:
Convergence = fopen('convergence.dat','r');
I am getting
Convergence = 3
but it should output something like:
Iteration Continuity Energy
1 0.302698 0.402993
2 0.470715 0.617098
3 0.507262 0.665507
4 0.469905 0.609844
5 0.407501 0.522219
6 0.362136 0.460129
7 0.321902 0.40361
8 0.337875 0.413282
9 0.357806 0.438051
10 0.380913 0.475059
11 0.389145 0.483145
12 0.272243 0.373424

fopen opens the file and provides a handle to the file (aka FileID). Once you've opened the file you will need to read from it using something like fgetl or fscanf? Alternatively you could also use readtable https://www.mathworks.com/help/matlab/import_export/ways-to-import-text-files.html. If the data file was saved from within Matlab you could also just load it.
