What is the matrix form for, say, A*x^2+B*x*y+C*y^2+D*x+E*y+F?
Tim, it is
exponents = [2 0; 1 1; 0 2; 1 0; 0 1; 0 0];
coefficients = [A B C D E F]';
What I meant to ask was, what is the correct output from coeffArray for that case?
@Tim The correct output from coeffArray for A*x^2+B*x*y+C*y^2+D*x+E*y+F should be [0 0 A;0 B D;C E F]
Shouldn't the single variable case be a row vector? "a matrix of integers with each row representing the exponents of one monomial" The test suite is representing it as a column. I guess you meant a matrix of integers with each row representing an exponent of one variable or with each row of size n representing the exponents of n variables.
