The overriding concept of makefiles is the ability to specify the dependencies in a simple tree. But since you are the one who knows which module(s) depend on which, you are the person who will need to create the tree.
If you get the original function back after the reverse, you have probably coded the transform correctly.
The problem is likely to be that your sampling rate is not a multiple of the basic frequency of sin(0.1*x). This means that you get a large FFT component close to the frequency, but you also get "noise" throughout the range, due to the fact that the residues do not cancel out.
I would try taking an FFT of sin(x), sin(2*x), etc., and see if these functions give the expected values.
Freedom is the freedom to say that two plus two make four. If that is granted, all else follows.

Thank You for the hint. I have tried with sin(nx), sin(2pi*x/n) and sin(2pi*x*n) too, but results were similar.
The most promising result was for the option with sin(2pi*x*n): here is a result with n=10. Values for x>270 are 0.
I used decimation in frequency FFT instead of decimation in time version, but it still doesn't show good values.
The exp function is inside function called "Shift".
As I wrote earlier, I don't use complex numbers library, so there are both tables for real and imagery parts. I used this relation: exp(i*phi)=cos(phi)+i*sin(phi).
Hello, I do not want to use an MDI app to create new documents of the same kind, like in text processors. Instead I want to be able to open different child windows from the menu. The menu handling is clear. When I go and create a new form with controls in the resources/dialog editor, how can I connect them to what I see in the client area of the child ? The classic kind of business software, you know. A user can open a customer window, then a payment window, a child for envoices, for banking, statics and so on. Normal dialog windows do not fill the client area, they are on top of all. That is not what I am going for. Thank You.
Hello. I got it now. To occupy an SDI/MDI with a formview resource template there is one detail in the project assistant. At the last page one can fill in from what the view derives. The preset is CView, but you must change it to CFormView. That was all. Well, I would have liked to make it an existing project, but this is ok, too. Thank You.
In my MFC application, I am doing a custom drawing in my dialog class OnPaint(). I have also created a few controls in dialog template. I have also resized and repositioned some of the controls in the dialog code. When I run my application, the controls are flickering.
Please suggest me how to avoid this?
CDC *pDC = GetDC(); //Get DC for Dialog's Client Area
pDCTmp->CreateCompatibleDC(pDC); //Create Compatible DC(pDCTmp) for Dialog's Client Area(pDC)
//pDCTmp is a member Variable
pBgBitmap->CreateCompatibleBitmap (pDC, 800, 640 ); //Create Compatible Bitmap(pBgBitmap) for Dialog's Client Area(pDC)
CPaintDC dc(this); // device context for painting
// TODO: Add your message handler code here
rect = rScreen; //rScreen is Client rect
pDCTmp->FillRect(rect,&CBrush(RGB(152, 185, 192))); //pDCTmp member variable is used to draw
//Custom drawings using the pDCTmp
