Select this check box to return solutions for which every subexpression of the equation represents a real number. This option assumes all parameters of the equation represent real numbers.

Select this check box to return a single solution (principal value). If an equation or a system of equations does not have any solution, the solver returns an empty symbolic object.

Select this check box to return the more general solution and the analytic constraints under which the solution holds. This option returns a structure with the fields parameters and conditions that contain the parameters in the solution and the conditions under which they hold, respectively.

Select this check box to express the root function in terms of square roots in the solutions. The results can be lengthy or less accurate for floating-point approximations.

Select this check box to apply purely algebraic simplifications, such as log(a) + log(b) = log(a*b) with the assumption that a and b are real positive numbers. Setting Ignore analytic constraints to on can give you simpler solutions, which could lead to results not generally valid. In other words, this option applies mathematical identities that are convenient for most engineering workflow, but do not always hold for all values of variables. In some cases, it also enables the Solve Symbolic Equation task to solve equations and systems that cannot be solved otherwise. For details, see Algorithms.

Select this check box to ignore assumptions on the variables to solve for. This option may include solutions that are inconsistent with assumptions on the variables to solve for.
