How can I use a function handle / anonymous function for fittype:

f = @(x,a) a+x;
fittype('f(x,a)')

??? Error using ==> fittype.fittype>fittype.fittype at 477
Expression f(x,a) is not a valid MATLAB expression,
has non-scalar coefficients, or cannot be evaluated:
Error in fittype expression ==> f(x,a)
??? Undefined function or method 'f' for input arguments of type
'double'.

I don't believe FITTYPE supports specifying a function handle as the
expression to be fit. For that I'd probably use LSQCURVEFIT from
Optimization Toolbox instead of FIT and FITTYPE from Curve Fitting Toolbox.
