Constraints with fsolve
显示 更早的评论
How would you all recommend setting constraints while using fsolve? I am trying to use it to solve a multi-variable equation, similar to using Solver in Excel (setting one cell equal to zero by changing several other cells). Could I use conditional statements?
Please note that I am not an experienced matlab user or programmer. (I've just finished my sophomore year in Engineering school.)

Fsolve CANNOT have constraints. The use of conditional statements inside your objective would often cause fsolve to fail to properly converge.

What about reducing the decimal places or reduce resolution (whatever you call it)? Say I have the output x(1)= 1.0000005823241514, x(2) = -4.511476108384046e-15. I just want x(1) to be 1, x(2) to be 0, how do I do that?

passing in initial values of type single() might help.
