I have the following data in a .m file. I realize this is bad but it is out of my control. I have looked into using fopen and fscanf to read the data. I can duplicate the exact data from the file but I only need part of the data. Please see the attached file for the data I want to read.
%read in data from file
fileId = fopen('pfoutput.m');
opPoints = fscanf(fileId, '%c');
I just want the numeric values.

fileId = fopen('pfoutput.m');
datacell = textscan(fileId, '*%f|%f/%f*', 'HeaderLines', 3, 'CollectOutput', 1);
fclose(fileId);
opPoints = datacell{1};

Variables are not stored in .m files as they are ASCII, Variables are usually stored in .mat files that matlab can read.
