| What f /. {a1x -> 20, a1y -> 5, b0x -> 0, b0y -> 0}shows is that f == p1 * (alx - 20) + p2 * (aly - 5) + p3 * b0x + p4 * b0yfor some polynomials p1, p2, p3, p4. The polynomials are given by [mcode]PolynomialReduce[f,... |
| I am not sure if Matlab does a bitwise operation, it may be more similar to In[2]:= Unitize[{2, 3, 0}*{0, 0, 3}] Out[2]= {0, 0, 0} In[3]:= Unitize[{2, 3, 0}*{0, 4, 3}] Out[3]= {0, 1, 0}Compare the last one with[mcode]In[4]:=... |
| Thanks to Mr.wayne wang and Mr. Shenghui Yang very much. With your help the problem can be solved.Once again, thanks to Mr. Simon Schmidt and Mr. Arnoud Buzing. |
