warning when solving nonlinear equations with 'solve'
显示 更早的评论
Hi everyone, Quick question: I'm trying to solve a nonlinear system of 30 equations in 30 unknowns using the solve function, and I continually get the following warning:
Warning: 26 equations in 29 variables. New variables might be introduced.
How should I interpret this in light of the fact that I'm specifying 30 equations and variables as inputs into solve?
Thanks in advance, John

Two possibilities come quickly to mind:
- You erred in coding them (look carefully and consider prettyprint), especially since it counts 29 variables and you mention there should be 30,
- The Symbolic Math Toolbox is simplifying them and eliminating some equations, so your simplifying them first could provide information.
Beyond that I have no idea.
