Details:

>>> h=@(x)1/x
h =

@(x) 1 / x

>>> fplot(h,[1 10])
error: operator -: nonconformant arguments (op1 is 8x1, op2 is 1x8)
error: evaluating argument list element number 1
error: evaluating argument list element number 1
error: evaluating argument list element number 1
>>>error: evaluating argument list element number 1
error: called from:
error:   fplot at line 44, column 11
>>>

The same statements work on Matlab.

This works however, where sin(x) is a built-in function.
>>> h=@(x)sin(x)
h =

@(x) sin (x)

>>> fplot(h,[1 10])
