Unable to read from text file

My textfile(sample pasted below) contains sequence of numbers.

Below is my snippet of code to read it:

   jointAngle = strcat('/mnt/seagate/dataset/RobotDemo/joint_angles/',jointAngles(1).name)
   fileID = fopen(jointAngle,'r')
   formatSpec = '%f';
   A = fscanf(fileID, formatSpec)

My output:

jointAngle= '/mnt/seagate/dataset/RobotDemo/joint_angles/1489512207.73.txt'
A = []

1) Why is my file not being read? 2) How can I convert this text content into arrays to plot a graph?

What error you get? You have to check your path...are you giving the path correctly?

Where in your code did you put:

A = []

If you put it after you read the file, you deleted everything in ‘A’.
