1. For x from 1 to 100, calculate y. Use fopen and fprintf to write x and y data into a file named “my_data.txt”. Then use fopen and fscanf to read the data. Show the data in two columns. Function to be used: y = e^(0.02x)

Thank you.

I apologize if i direspected this forum in any way.

Was my first time here and I just rolled the ball to see what would happen.

And with regards to my question I did proceed to do it. However, I recieved an error message regarding preallocating the line.

I looked up a way of preallocating in matlab, however, not sure how to do it with this specific line.

Got an answer but still have that one error. Attachment below.

Greatly appreciate the feedback.

Thank you.

Please don't post homework problems without showing your attempts and asking specific questions. I'm feeling generous, though, so:

• Learn the basics of MATLAB: https://www.mathworks.com/learn/tutorials/matlab-onramp.html
• Documentation for fopen, fprintf, fscanf

Terminology: that's a Code Analyzer message, not an error. These may help you improve your code, but they don't need to be resolved (and in some cases are just useless). See here for a guide: https://www.mathworks.com/help/matlab/matlab_prog/preallocating-arrays.html. You've got basically the example.

Note for questions: most of us don't like looking at attachments. If you've got code to share, put it in a code block (Alt-Enter)
