Hey Olmar
The errors you're encountering seem to be related to symbolic computation in MATLAB, specifically when using the 'dsolve' function. This can occur due to a variety of reasons, such as syntax errors, incorrect input, or issues with the symbolic engine.
Following some steps you can take to troubleshoot and potentially fix these errors:
- Make sure all variables and functions are properly defined using syms.
syms y(t)
- Ensure that you are using the dsolve function correctly. Here is a basic example:
syms y(t)
Dy = diff(y, t);
eqn = Dy == -y;
sol = dsolve(eqn);
- Also, make sure you are not using any MATLAB reserved keywords. Adding MATLAB documentation for your reference: https://in.mathworks.com/help/rtw/ug/reserved-keywords.html
Kindly provide more information to debug further.
Thanks
