simultaneous equations

how do i simultaneously solve a pair of equations, one being exponential and one linear?

Answer 1

[Sean de Wolski]

If you have the Optimization Toolbox:

doc fsolve

If you have the Symbolic Math Toolbox:

doc solve

Answer 2

[Walter Roberson]

Note that many such pairs will not have a useful analytic solution. The pairs that do will generally involve the LambertW function in the solution.

This lack of useful analytic solution would tend to lead people to use fsolve() to get a numeric solution. Unfortunately fsolve() only looks for one solution but there might be multiple solutions.

Is there a general form of the equations? Will they perhaps even always be the same form except with different coefficients?
