How to solve polynomials in matlab

WebDec 1, 2010 · Matlab is screwed up, but the syntax is sol = solve (eq1,x1,eq2,x2,..); It would make more sense to make it solve ( {eq1,eq2,..}, {x1,x2,..}) but no, we have to write out all the arguments one by one. Anyway the trick is that eq1, eq2, .. are symbolic expressions that must be evaluated to zero. WebFeb 17, 2024 · As the equations are not clear in the data provided, let me simplify and finalize the equations to be solved. First equation: 2*x (1) + sin (x1) Second equation: 2*x (2) + sin (x (2)-1) - 2 Now the equations are solved using fsolve command as shown.

WebDec 10, 2024 · You can vary three parameters, c, n and w. You can choose one of the three target functions involving the coefficient c. f 1 ( x) = 1 1 + c x 2 f 2 ( x) = e − c x 2 f 3 ( x) = c x The parameter n is the number of interpolation points in the interval [-1 1]. The degree of the interpolating polynomial is n − 1. WebAs @rayryeng said, that is only possible if you know the value of the other variables, is so, you can declare f as an anonymous function and use fsolve () like this: f=@ (x) ( (cos (x)*sqrt (2^2+3^2)-4*sin (x))/ (cos (x)-1)-5/x); fsolve (f,0.1) but using your correct values.
