MATLAB: Matlab give me error when i use fzero to calculate zero of function

functionroots

fzero of function

fun = @sin; % function
x0 = 3; % initial point
x = fzero(fun,x0)

Just go to the file location and rename the file as myFzero.m for example.

x0 = [1 2];
fun = @(x)sin(x)-0.703*x;
sol = fzero(fun,x0)

you need to rewrite so that the given equations are equal to zero. Then fzero finds x.

fun = @(x) something with x equal to zero
x0 = some starting point
res = fzero(fun,x0)
