I thought setting the Jacobian to be sparse would make the solver faster? I'm not sure what to try next. 댓글 수: 8 이전 댓글 6개 표시 Torsten 2023년 8월 2일 편집: Torsten 2023년 8월 2일 MATLAB Online...

MATLAB Online에서 열기 It is not possible to calculate the jacobian of a symbolic function w.r.t. another symbolic function directly. According to the "jacobian" documentation page here: https://www.mathworks.com/help/symbolic/sym.jacobian.html#bt9oivx...
Open in MATLAB Online Ran in: In my code, I have a set of x and y data points, called xdata and ydata respectively. I am trying to use lsqcurvefit to find the value for a quantity in the model that should reproduce the data. The problem is that the mode...
You will also need to change your boundary condition function. Or actually, since you never use it except in the definition of the anonymous function bc and never use that anonymous function, just eliminate bc and your boundary_conditions function entirel...
Try another initial guess vector and see if the solution changes. Usually "fsolve" should detect that a system of equations is underdetermined (more variables than independent equations as in your case). The error message would be "Singular Jacobian detected". Sign in to co...
