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. 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.
