hello, I am new to matlab. I would like to change polynomial z=c1+c2*x+c3*x^2+c4*y+c5*y^2+c6*x*y+c7*x*y^2+c8*x*y+c9*x^2*y*2
to matrix. I have a problem with matrix A to get sum of x,y into A.
for i=1:9
syms x,y
A(i,1)=1;
.
.
A(i,9)=x(i)^2*y(i)^2;
end
Thank you for your time.

If this is not you are expecting..read about polyval.

Thank you for your answer, KSSV. But, this is not my expected answer. I would like to build the matrix A with polynomial values ( x and y).
