Array indices must be positive integers or logical values.

Hello all, how are you?

I am trying to write a program to calculate some aerolasticity stuff, here is what I have so far:

I am fine, hope you are fine too!

In MATLAB, there is no implicit multiplication. In the line

f22 = ......

There is a missing multiplication operator after 'a'. It should be like this

8*a*(1i ...
  %^ this is missing

Also, it is better to write your code in a MATLAB script or function: https://www.mathworks.com/help/matlab/matlab_prog/scripts-and-functions.html. MATLAB gives much clear error message which makes it easy to debug the code.

Problem Solved ! Thank you so much !

I will have more questions as I build my program... Can I post it here instead of creating new topics ?

You can post a new question and paste the link in the comment. I will get the notification, and if I am unable to answer, someone else probably will.
