The terms of the divisor polynomials are ordered according to a certain term order. Solving quartic equations using Matlab. mrdivide imposes a termination criterion to truncate the degree of the quotient polynomial. A polynomial is an expression that is made up of variables, constants, and exponents, that are combined using mathematical operations such as addition, subtraction, multiplication, and division (No division operation by a variable). Polynomials are equations of a single variable with nonnegative integer exponents. In case vectors are coefficients of two polynomials, then function deconv gives polynomial division and it returns the quotient as well as remainder.
