Hi Guys, I don't know if I make sense but please try to help me. I am working in Matlab. I have multiple line segments of different lengths with end point coordinates. I want to split each major segment into multiple minor segments in a way that all segments will have same length...

Dear Studiot, Thanks for your help. Now I have almost solved my problem. Kind Regards,

Dear Studiot, My question was not emphasized on CW or ACW. I know that if I invert the sign of 'sin' in the matrices you mentioned, the direction will be changed. I actually want to ask why I need to rotate in X-axis for second rotation rather than Y-axis when actually the rotation around...

Dear Muphrid, Thanks for the reply but your reply is too complicated for me. Can you please explain.

Dear Studiot, Thanks for the reply. This is actually a further explanation of what has already been said and understood. Thanks for this anyways. The difficulty I am facing is as follows: I rotated my coordinates first around Z-axis, 90° CW. This mapped +ve y-coordinate onto +ve x-coordinate...

Dear Studiot, I have points (in Cartesian coordinates) and I know the desired angle (α,β,γ) on which I want my points to be rotated. I want to get the rotated points i.e. P2 in your example. For example, P1(1,2,3) has to be rotated around principal axes XYZ at angles (α=10,β=20,γ=30). What...

Dear Simon, You are referring to the same Wikipedia article. If it is the same then please explain because I am not getting what I intend to.

Hi Filip, I am sorry that is what I don't want to do. I tried to explain in my post (may be not explained in a good way) that this method is used when you want to rotate the principal axes. I want my principal axes remind fixed. I rather want to rotate my body (defined by Cartesian...

Hi Guys, Sorry I am not going to reply to the question above but I have another problem regarding my task. I hope you don't mind to reply. My problem is as follows: I want to rotate a 3D body around an arbitrary axis with fixed principal axes XYZ. The solutions I found is with Euler angles...

Dear All, I have come across with a seemingly very simple problem but could not solve it by searching on internet and books. May be I am confused. I want to rotate a 3D body around an arbitrary axis with fixed principal axes. The solutions I found is with Euler angles (Euler rotational...

Hi, I have been trying to run a linux executable (written in fortran77) into my another code (also in fortran77). In Matlab, I did it with "system('./<filename>')". But I am not able to do it in fortran script as './' is not simply working for me. I will really appreciate if anyone could...

Hi all, Can anyone tell me how can I convert lat, long & height to azimuth, elevation & range? I found some calculators online but I need mathematical formula please. Kind Regards,

Hi guys, I am going to ask another very stupid question. But surprisingly, I could not find any help on it on internet. My question is: I have defined a function which doesn't take any any input and one output. When I called it, the program halts. I have checked the function and it is...

In my view 2D corresponds to (row, column). I found the data in the file in the same manner i.e. in rows and columns. How would you define a 3rd dimension in that data file no matter how the arrays were defined in the dimension statement? PS: This is not my question this is actually matlab's...

Actually I am working on a code that has been written by someone else and I found 'rfac(X)' in that code. The code is written in Fortran and I am trying to use it in Matlab. I have checked everywhere but could not find any function named 'rfac'. I hope I am clear now.
