about the equation solve, this simple complex equation can be solve with Solve, while the domains of a and b must be added. In[152]:= Solve[{a + b I - 2 + 3 I == 0.0 + 0.0 I, -100 > Out[152]= {{a -> 2., b -> -3.}} but if the...
Actually, I want do numerical integration, I use the Simpson method, the integration in on k and w, so there are two loops. I use Table to replace the for loop, but the speed almost the same. I also write the Matlab code, it's much fast. this result...
