> Hi, I have been trying to solve a system of differential equations in Julia. I have run into a few problems and am not clear on what I am doing wrong. Problem definition: The system I am working on is a model of the immune system. This is represented by 9 differential equations. One of the parameters is time-dependent and is a step function representing the lifetime of an infection in the immune system. This makes the system discontinuous at the time of entry and removal of the infection. To …
