    Syntax

    tf = ne(A,B)
    tf = (A ~= B)

    Description

    tf = ne(A,B) compares Laurent polynomials A and B and returns 1 (true) if the two are unequal and 0 (false) otherwise.

    example

    tf = (A ~= B) is equivalent to tf = ne(A,B).

    Examples

    Open Live Script

    Create two Laurent polynomials:

    • a(z)=2z3-3z2+4z-5

    • b(z)=4z3-6z2+8z

    a = laurentPolynomial(Coefficients=[2 -3 4 -5],MaxOrder=3);
b = laurentPolynomial(Coefficients=[4 -6 8],MaxOrder=3);

    Confirm a(z) and b(z) are not equal.

    a ~= b
    ans = logical
   1

    Confirm 2a(z)+10 and b(z) are equal.

    c = rescale(a,2)+10;
eq(c,b)
    ans = logical
   1
