    To turn trackball technology into a 1-2 inch sized heavy duty unit able to be used for a quieter and smoother replacement for a ball transfer unit. It also must have a performance weight capacity for 90lbs minimum.Was thinking taking a typical plastic design and turning it into a more solid metal structure with also smoother/harder surfaces for the ball to roll on.

    I have a set of 14 nonlinear equations to solve. I used lsqnonlin to solve them but I am failing in making it converge. This can be attributed to the large difference in value among the 14 unknowns. The solution can range from 1e-10 to 1 across the 14 parameters. I tried all tricks I know to overcome this problem but failed. You are free to use a different solver, write your own solver or normalize the equations in the way you like. The main code is a bit ling but you shouldn&quot;t care about it. All what you need to care about is the 14 equations at the end of the TRIAL_7 code and the caller subroutine for solving the equations. I attached also an excel sheet you approximate values of what some of 14 unknowns should be. These are just approximates of the solution. We can try solving the provided example and if we succeeded then we can try different examples to make sure that the code works. Please check the codes and try playing around with it before bidding. I will happy to provide any extra details and clarifications once needed.
