Solving Transcendental Equations

3 views (last 30 days)
Dear all,
I am trying to solve the following transcendental equation using 'solve':
[y]=solve((a-((x+b*x)/c)-(p*(exp((x+b*y)/(d))-1))-(q*(exp((x+b*y)/(2*d))-1))),y)
And I get the following result:
=========================== Warning: List of equations is empty. > In solve at 70
i =
[ empty sym ]
================================
What does this really mean? Is there something wrong with the equation?
Any help to solve this would be much appreciated.
Thanks,

If you happen to have defined values for any of those names, and one of the values is the empty array, then the expression overall would become the empty array, leading to the warning that you see.

What version are you using? This does give me a result with 2012a.
