My two questions are:
  1. Why are you using an inline function?
  2. What have you tried yourself?

f = inline('sin(x/2)')
g = @(y) 2*cos(y)
x = 0:0.1:2*pi
y1 = sin(x/2)
y2 = 2*(cos(x))
[AX,L1,L2] = plotyy(x,y1,x,y2)

Looks like you solved the problem by your comment above? Did you read the documentation of fplot?? It belongs to symbolic math toolbox used to define variables symbolically.
