How anyone solve missile equations of motion

[Tensor123]

please post me fast calculus with fast sampling
ca. 60 seconds of missile direction choose.

Since this really isn't a Studyworks problem, you probably should have posted in the Mathcad Collab.

In any case, your file only contains a rotation matrix, which, if you removed the outer brackets, will at least symbolically evaluate the matrix multiplication.

However, you don't have anything else in the file. I suggest that you do a websearch for solutions for model rockets that other people have constructed.

Sorry , my reference are books "Missile Guidance
and Control Systems" Author: George M. Siouris
and "Missile Aerodynamics" Author Nielsen J.N. - [McGraw Hill 1960], and regonal speciphics of publications, not web search engine results.

But all your sciencers models are to slow.

The models are slow because the math is complex. The general equations require solving a multidimensional partial differential equation at each time step.

If you don't care about accuracy, you can simplify your models and run coarser time steps.
