Abstract :
In certain applications, the independent variables of a given two-dimensional (2-D) rational function have to be transformed by substituting every variable with a specific rational function of two variables. Based on two known algorithms suited for one-dimensional (1-D) rational transformations, two useful algorithms are presented to perform general 2-D rational transformations. To compare the computational efficiency, the authors consider the number of multiplications used in both 2-D algorithms
