Hello, I have a text output from a terminal program which reads data from a PID controller as shown below. How do I take the relevant data terms from the text and properly place them into respective arrays? Relevant data is essentially each numerical value

FID=fopen('File_name','w');
That would ask to creat a new file named File_name or erase the content of an existing file with that name.
The file would be empty, and fscanf() would produce no data.
I suggest you consider fileread() or readlines()

Hi Nicholas
I understand that you are trying to numerical value from a text file. This can be achieved by using 'regexp' function of MATLAB . This function is helpful for extracting specific patterns from text data, including the numerical values.
For additional information regarding 'regexp' function please refer to the following documentation:
I hope it helps!
