How to define a constat in function handle?

Hello,

Suppose I have to define a polynomial with function hadle of f(x,y) = ax^2+by+c with a, b, c as constants. So I can do the other mathematical operations likr integration, differentiation with this function handle.

Please note that I dont want to define the constants as numbers like f = @(x,y) 3x^2+4y+5.

Could someone please help me?

Thanks and regards

You mean like this?

[a,b,c]=deal(3,4,5); 

f = @(x,y)a*x.^2+b*y+c

f = function_handle with value:
    @(x,y)a*x.^2+b*y+c

Or like this?

syms x y a b c f(x,y)

f(x,y)=a*x.^2+b*y+c

f(x, y) =

The symbolic one. That was the command I was looking for.

Thanks you.
