Hi Diana,
Equations can be inserted interactively in the Live Editor. However, for LaTex equations, LaTeX expression dialog box should be used. To do so,
- Go to the Insert tab, click Equation, and select LaTeX Equation.
- Enter the below expression in “Enter a LaTeX equation code:"
A=\matrix{1 & 0 \cr 0 & 1}
You can find more details on the same in the “Insert Equations into the Live Editor” documentation. To access the documentation, type the following two commands in the Command Window of installed MATLAB R2020b:
addressString = 'matlab/matlab_prog/insert-equations.html';
web(fullfile(docroot, addressString));
I hope you find this useful!
