Hi Guillermo,

I understand that you want the commands to get laplace of a differential equation.

Please refer the following code for a working example in MATLAB.

syms t Y(s)

% Define the differential equation
diff_eq = diff(Y, t, 2) + 2*diff(Y, t) + 2*Y == 0;

% Take the Laplace transform
laplace_eq = laplace(diff_eq, t, s);

% Display the Laplace transform
pretty(laplace_eq)

2 Y(s)
------ == 0
   s

Please refer to the following documentations for more details on the functions used in the example mentioned above:

• syms - https://in.mathworks.com/help/symbolic/syms.html
• laplace transform - https://in.mathworks.com/help/symbolic/sym.laplace.html
• pretty - https://in.mathworks.com/help/symbolic/sym.pretty.html

Hope this helps.
