description:isneq=ne(f, g) is called for the syntax 'f ~= g' and compares matrices of NCpolys f and g elementwis. It returns a matrix of the same size with entries set to logical 1 where the polynomials are not equal and entries set to 0 where they are equal. Matrices f and g must have the same dimensions unless one is a 1x1 matrix. A scalar can be compared with any size array. arguments: f and g are NCpolys representing polynomials or matrices of NCpolys with matching dimensions. output: matrix with elements equal to logical true (1) or false (0) possible usage:f ~= g, ne(f, g) examples: >> [x*x-x*y-y*x+y*y,x+1]~=[(x-y)^2,y+1] ans = 0 1 |
