I need to solve a very complex equation (in fact it's a 4x4 characteristic equation), but the matix is too complex even with BESSEL, HANKEL functions of the vaiable{variable is also outside bell, hankel functions}, Because of it's complexity, I want to use iterative method: i assume a initial value to the variable, and compute the bessel, hankel function, substitute into the equation and solve for the variable,compare the initial value to the solved value and continue iteration till the solved variable match with my assumed one. But to realize this in LABVIEW seems a little difficult, because I don't know if I can allow LABVIEW compute the determinant of the matrix which is the function of the variable( or eigenva
lue which I'm seeking here).
