Hi Lars-Martin,
MATLAB supports Vectorizing of your code, so you don't necessarily need to use any looping function.
You can import your data using load() if its a .mat file or readtable() for other files such as spreadsheets, text files etc.
And then accordingly you can pass the data to the built in functions such as standard deviation, exponential, average (mean), logarithm etc. that you might need for your problem statement.
