for exmple, i have 2 or more equation (a and d), with some variable defined (B and C).
then, i want to solve :
f=@(x) (a=B*x) (d=C*x^2) sqrt(a+b);

Using anonymous functions:
Fa = @(x) B.*x;
Fd = @(x) C.*x.^2;
Fh = @(x) sqrt(Fa(x)+Fd(x));
Using the symbolic toolbox:
a = B*x;
d = C*x^2;
s = sqrt(a+d)

f=@(x) B*x +C*x^2;
% d=@(x) C*x^2

To answer your original question as phrased:
I suspect that you could do that with careful use of having the anonymous function invoke evalc() with a character vector that was a command line that used evalin('caller') to retrieve the parameter, and assingin('base') to save the variable, and then a series of assignin('base') and evalin('base') calls.
This would not be recommended even a little, but you did not ask for our recommendations, only for how to do that task using multiple statements inside an anonymous function.
The approaches shown by Stephen are much better. I would have to have a really good reason to use the approach I outlined above, at least for anything other than proving it could be done.
