Using Matlab's fzero and fplot with an inline function

EDUğ f = inline('exp(-4.5*x)-x/200')
f =
     Inline function:
     f(x) = exp(-4.5*x)-x/200

EDUğ fplot(f,[1,2])  % generates quick plot

EDUğ fzero(f,1.5)   % finds root near 1.5 or if 1.5 replaced by vector
Zero found in the interval: [1.02, 1.8394].

ans =
    1.1469
