2variable Given... Find involving complex matrix determinant Hi,I'm doing a quasi-static wing flutter analysis.I annotated the attached worksheet a bit but the basic idea goes like this:My objective is to find a critical value for k and X as follows: A, B, D and E are functions of k and X.They are coefficients to a series of two equations such that:A*h + B*j = 0D*h + E*j = 0where h and j represent another function (not shown in worksheet) - h and j both > 0.Thus for a solution the determinant of matrix:ABDEmust = 0. This is where things get a bit complicated.The suggested approach here is an excel job of many columns and some linear interpolation (groan):Set k = some initial guess (2)Calculate numerical values of those coefficients A, B, D and E in terms of XCreate two equations from the determinant = 0 condition - real and imaginary parts.Solve to find X which typically has two real solutions and one imaginary (though could also be three imaginary potentially).(Effectively) repeat for other values of k using a guess-and-correct approach unti
