Is it possible, to build a symbolic expression with symbolic parameters/variables like in the minimal example below?
syms x y
syms j % index var
m = 10 % max index

p_j = sym(‘p’, [m 2]) % symbolic parameter vector
phi = sym(‘phi’, [m,1]) % symbolic vars

syms J_j(j) % helper expression
J_j(j) = sqrt((x-p_j(j,1))^2+(y-p_j(j,1))^2)*phi(j); % <-fails

J = symsum(J_j(j), j, 1, m) % final expression
The error is probably due to accessing a matrix.

I very much appreciate any response.
