I would like to import data from my computer using the following function :
fileID=fopen('C:\Users\Emma Vos\Documents\MIWB\OT4\GE\1_16 jaar data.csv','r');
I do not succeed. The program gives me the error : Error: The input character is not valid in MATLAB statements or expressions.
What is it due to ? how can I help it ?

Matlab error message is certainly not helpful.
The issue you have is that there is an invisible unicode control character (U+202A, which is meant to force text to be interpreted as left-to-right) before your first '. I can't tell you how it got there, it's been created by whatever you've copied the string from.
The fix: type the first part of the command and only copy/paste the path itself without the enclosing quotes. You should obtain the following which, although looking the same, does not contain the offending invisible character:
fileID =fopen('C:\Users\Emma Vos\Documents\MIWB\OT4\GE\1_16 jaar data.csv','r'); %This string has no invisible control characters

csvread is more useful. Please try.

While csvread would indeed make parsing the file a lot easier, the issue reported here has nothing to do with the way the file is read.
