            For improving the speed, you can see Numba, which is useable if you use NumPy a lot but not every code can be used with Numba. Apart from that, the formulation of the equation system is confusing. You are solving 3 equations and adding the result to a single dydt list by 3 elements each. You can simply create three lists, solve each equation and add them to their respective list. For this, you need to re-write my_system as:

            GEKKO: Error in syntax of function string
            Asked 2022-Jan-15 at 05:50

            I'm having trouble understanding an error message I'm getting from my GEKKO model.

            For context, this model is supposed to optimize the gas spring force and dimension parameters of a gas-spring assisted door to minimize the operator force required to close the door. My intent is to calculate the required force at a series of angles between 0 and 90 degrees, then sum the absolute value of the force at all angles and minimize that value. There is also a constraint on the gas spring length so the optimization doesn't come up with unrealistic dimension parameters. I've defined the force and other values that need to be computed at each angle as lists of Intermediate variables.

            The error appears to be related to one of these lists of Intermediate variables, but I don't know how to interpret "Position: 2" in the error message, let alone "Error in syntax of function string". I've searched in some other answers on here, but I haven't found a clear answer on how to use this position information to troubleshoot the model. What is the message trying to tell me?

            As noted above the if(keyPressed) needs to be removed. The following works on my system. I changed the images to some that I had for testing purposes; you'll need to change them back for your setup. I also added an extra display function to simplify things a little. There is likely more optimization that could be done. Make sure that the _imgW and _imgH values are correct for your images.
