MATLAB: Unable to use the sqrt(A) function in a function file

Question

I'm trying to execute a function similar to this:

function y=y(w)
a=1
b=1
c=1
d=1
e=1
f=(b*c)*a^3
F = @(x) x^2+sin(x/2)
funct = sqrt(5)+sqrt(F)

I have more code after this but I get an error before this section shown below

Undefined function 'sqrt' for input arguments of type
'function_handle'.
Error in y (line 9)
funct = sqrt(5)+sqrt(F)

Can someone help me with what to do here? Ive tried changing the sqrt to ^0.5 or ^1/2 but it still won't work.

Answer 1

F is your function handle ,how could you pass it as parameter to sqrt?? Probably,you want to do this:

sqrt(F(5));
