Stuck in [PP,SPP]=OptimiseAlgebra(PP,'SPP');

[huyang8911]

Matlab R2021a, run m files "GenerateNavFilterEquations.m", stuck in [PP,SPP]=OptimiseAlgebra(PP,'SPP'); I have spend about 30hours run this code. The index loop to 7800, and still not finish. I have updated the function "OptimiseAlgebra". Any one known where is wrong?

Somehow in the newer versions, the OptimiseAlgebra script gets stuck in a loop while establishing the subexpressions for the covariance matrix ([PP,SPP]=OptimiseAlgebra(PP,'SPP')). What worked for me was changing the condition if f_complete || index > 100 to if f_complete || index > 500. After this change, my script successfully runs in about 2.5 hours
