How do I merge function handles?

Question

suppose I have 2 function handles to evaluate

for i=1:90

f= @(x)x^3*sin(i)

and

g=@(x)x^2*cos(i)

end

the functions i have are far more complicated. now suppose i want to merge them to obtain f+g, i.e. a single function

@(x)x^3sin(i)+x^2cos(i).

How can i do that without combining the expressions but only using f and g?

thanks for the help

@(x) f(x) + g(x)

In some cases, you can use

syms x
matlabFunction( f(x) + g(x), 'vars', x)

If there are no captured variables, then you can use string manipulation on char() of the handles.
