You can use latex to insert equations in the live editor. See here: https://www.mathworks.com/help/matlab/matlab_prog/insert-equations.html

Thanks for help. I used LaTeX equation to create a matrix with Greek letters and call it A. Now I need to find its inverse, my question is that how can I insert the matrix A in the command window in order it find its inverse?

[Ameer Hamza]

If you want to do mathematical operations, you need a symbolic toolbox and write it as code instead of latex. For example, run the following code in the live editor

syms alpha beta gamma mu omega

A = [alpha beta^2 gamma*alpha;
     mu gamma alpha;
     omega^2 alpha^2 mu*alpha];
 
inv(A)

[Arwa Alwatban]

I used the code that you provided but the inverse with Greek letters interies become as follow:

the inverse of the matrix does not appear as symbol of Greek letters

Which MATLAB release are you using?

[Arwa Alwatban]

it is MATLAB R2020a

[Ameer Hamza]

Can you paste the code you are typing in the live editor?

[Arwa Alwatban]

A=\matrix{\omega_F & \alpha & \cr -\omega_F & r_F+k_F+\delta_F }

This is the matrix I wrote using LaTeX equation.

 sympref('TypesetOutput','default'); % at the beginning and try again with Ameer’s code

Arwa, not in latex mode. In the previous comment, I asked to run the following code in the live editor. You need to paste this as code

syms alpha beta gamma mu omega
A = [alpha beta^2 gamma*alpha;
     mu gamma alpha;
     omega^2 alpha^2 mu*alpha];
 
inv(A)

Now it works. Thank you very much Ameer.
