Please help me normalize this library system. im confused when doing normalization
I think no need column for "Borrowername" in Borrow table as we link it with student.

I'm trying very hard to understand this code about a Deep Learning-Based NOMA system based in MATLAB. I am really new to MATLAB coding but I really need to understand this entire code as it will help in my school project and I am struggling.
I think as of right now I do not need to know how the mathematical formulas work, but instead, the focus is on what the code is doing and its flow.
This is part of the code in the trainData.m file that I am struggling with right now
Why are the pilot symbols calculated and then replaced right after?
Why is the idx_sc (20) selected to be replaced? What is its significance? Is it the only subcarrier selected for the training of the DL model? Why only that?
This portion of the code in the picture is labeled "generate training data for each class". From my understanding, it is generating OFDM packets for each label, simulating the transmission and reception, and then getting the features and labels for each of the 16 classes. Is that correct?
The code and all relevant function files can be found in the link below.
Please help me understand the code!!! Please! Much thanks!

To get you started, In lines 91 the code initializes the entire variable as 0. Subsequent lines (92-96) are just replacing pieces of the variable based on the indexing inside the “(…)”
I am new to the Neuroscience topic and I am supposed to baseline correct some EEG data that I have already epoched. I have been googling to try to find out how to do this on Matlab but I am not sure what the concept is. Can anyone help? I know it's a very general question but I am not sure what to ask. If someone can point me in the right direction or even tell me how to do it, I'd be very thankful.
You have to subtract the mean of the first samples of every channel from the whole length of the channel. Typically the baseline window is 100ms or more before the event.
Does anyone know of a method to decode this sort binary file. It should have a quite simple structure, a couple of lines of headers and then just grid data. I have the Vertical Mapper software but I want to cut out a step in my modelling process and do everything in matlab??
Any tips are appreciated.
Thanks
Alex
You'll need the Mapping Toolbox for that.
I am implementing an app which measures the how much distance it has moved .For example if my device felldown from my table to ground ,then I would like to calculate the distance.So Kindly help me to do this. Let me know if my question is not clear.
Thanks in advance.
Your question is very clear : you want to compute the second level integral of the acceleration, which theorically is possible, by supposing the speed null at some time, but I really doubt you could get something precise enough to make any sense (as in many integral computations).
This isn't done today because the error is too big. Done in hardware (for permanent integration of the acceleration) it could be a little more precise but probably not enough to really compute a distance in any acceptable sense of the word "accuracy".
If you want to try it by yourself, here's a document describing more in detail the approach : http://perso-etis.ensea.fr/~pierandr/cours/M1_SIC/AN3397.pdf
I am new to this Post. Kindly let me know if I make any mistake the way I am asking question.
My question can be clearly understandable when one can go through these links where I have explained what I am looking for.

The major point will be "How Can I create such a 'Variable FIFO buffer' whcih depends on input period & Filter sampling frequency 'Fs'?
If any one out there has any Idea or soultion for such a problem, Then I will be very glad to know and it will help me a lot in my project here.
Sincerely
Prashant
Maybe I don't fully understand what it is you're looking for here but I think you already have all the information that you need.
Fs = 1000; %% or whatever your sampling rate is to begin with.
Order = 3; %% Or whatever order you decide to work with.
Buffer_length = (Order/2)*Fs; % this will be the amount of data in each buffer
If you're looking for someone to give you anything more than this you're going to have to provide additional information and show what you're tried to do so far.
