In this work, we have describe the application of kronecker product operation to interpolation the functions of higher dimensions ( 3 and 4-variables function) by using least square method . Several examples are given to illustrate which is used to define and specialize the method. A comparison between the exact function and interpolation function depending on least square errors.
