First, solve **the quadratic equation without specifying** a variable. The order in which you specify these variables defines the order in which the solver returns the solutions. If you do not specify var, the symvar function determines the variable to solve for. This condition means the parameter k must be an integer.

Thanks for the help everyone regarding the uninstalling and getting my browser back to normal! Thus, the solutions in this mode might not be correct or complete, and need verification.Ignore Assumptions on Variables The sym and syms functions let you set assumptions for symbolic variables. More Aboutcollapse allTipsIf solve cannot find a solution and ReturnConditions is false, the solve function internally calls the numeric solver vpasolve that tries to find a numeric solution. For example, a solution is x = pi*k - asin(3^(1/2)/3), and y = 2*pi*k - 2*asin(3^(1/2)/3), with the parameter k under the condition in(k, 'integer'). my site

The generated parameters do not appear in the MATLAB workspace. solve chooses x to return the familiar solution.

If a single output argument is provided, conditions is returned as a field of a structure.

The number of fields in the structure correspond to the number of independent variables in a system. In the latter case, solve also issues a warning indicating the values of parameters in the returned solutions.If a parameter does not appear in any condition, it means the parameter can Flag Permalink This was helpful (0) Collapse - Re: Search Bar in Internet Explorer changed by Donna Buenaventura / October 29, 2004 10:45 AM PDT In reply to: Re: Search Bar NetCaptor is also excellent!

Substitute k with 4 to obtain a solution for x. Check if the value chosen satisfies the condition on k using isAlways.Check if k = 4 satisfies the condition on k.isAlways(subs(cond, param, 4))ans = logical 1isAlways returns logical 1 (true), meaning Sorry, there was a problem flagging this post. example[`y1,...,yN`

If ReturnConditions is false, the solve function either chooses values of the parameters and returns the corresponding results, or returns parameterized solutions without choosing particular values.

Setting IgnoreAnalyticConstraints to true can give you simple solutions for the equations for which the direct use of the solver returns complicated results. In this case, the number of variables that symvar finds is equal to the number of equations eqns.
