But with ode15s before specifying the jacobian sparcity it was as quick as 1 minute, which would be much better for when I move to a bigger grid, but I'm blocked by the "array exceeds maximum array size preference" error unless I can get t...

My calculation of F(x) yields F'(x) for no additional cost in computation because I use AD. So when the solver asks for an F(x) update, is it OK to update F'(x) at the same time and ignore subsequent calls to upate F'(x) ? We would need to be...
Hello, In my evaluate() function, I need to decide whether to compute the residual and Jacobian matrix based on a certain if condition. Specifically, I am optimizing state variables including a rotation matrix R and a translation t, and ...
To define dots in Latex, use: \ ldotsfor horizontal dots on the line \ cdotsfor horizontal dots above the line \ vdotsfor vertical dots \ ddotsfor diagonal dots Here are some examples: \[\Sigma=\left[ \begin{array}{ccc} \sigma_{11} & \cdots & \sigma_{1n} \\ \v...
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 model equation includes an integral,...
