The main difference between these two types is that the ndarray can be any number of dimensions, while the matrix is limited to exactly two dimensions. For ndarray, all operations such as addition, subtraction, multiplication, exponentiation, and division operate element-wise. However, for the ...

It calculates if the problem can be convex by checking if the matrix is positive semi-definite. It also calculates the condition number for each phase thanks to the eigenvalues. If everything is okay, let us solve the ocp ! Solving the ocp It is now time to see Ipopt in action! To ...
