Is there a maximum number of equations that can be solved using symbolic (solve function)?

Hello, I am trying to solve 190 equations using matlab solve function and I am getting: "Warning: Explicit solution could not be found." So I wonder if there is a limitation on the number of equations.

Thank you in advance,

If there is a limit, then it is much larger than 190. At least 32000 I would expect.

Explicit solution could not be found can occur even with fairly simple expressions. For example,

solve(sin(x)-x/4, x)

will not have any explicit solution.

You did not indicate anything about the properties of the equations. If they are linear equations, did you test their rank() ?
