How Can I put some numbers in a sym and sum its cells?

I have the matrix [A]= [ a*(x^2)+y , b(y^3)+x ; d*(x^2)*y , c*y ].

and I have the matrix [B]=[1 2;3 4] which the first column of [B] is x and the socond culomn Of [B] is y .

I want to put x=1 and y=2 then x=3 and y=4 and sum A11. then do it for other cells.

a , b,c,d are symbolic variables.

Answer 1

[madhan ravi]

syms a b c d 
B = [ 1 2 ; 3 4] ; 
x = reshape(B(:,1),1,1,[]); 
y = reshape(B(:,2),1,1,[]); 
A = [ a*(x.^2)+y , b*(y.^3)+x ; d*(x.^2).*y , c*y ] ; 
a = arrayfun(@(z) sum(sum(A(:,:,z))), 1:size(A,3),'un',0);
celldisp(a)

Answer 2

syms a b c d 
B = [ 1 2 ; 3 4] ; 
x = B(:,1) ; 
y = B(:,2) ; 

 A = [ a*(x(1)^2)+y(1) , b*(y(1)^3)+x(1) ; d*(x(2)^2)*y(2) , c*y(2) ] ; 
 
 iwant = sum(A(:))

[masoud jiryaei]

excuse me you i mean : A11=(a*(1)^2 + 2)+(a*(3)^2 + 4)

A12=...

A21=...

A22=...
