speed up execution of matlab code

Hello.
I already make matlab code and some functions.
When I execute matlab code, it took 247seconds on my laptop.
The speed is very slow.
I want to speed up the execution of matlab code(cpa_code_final) and some functions(cpa_calc, cpa_loc, dcpa_tcpa2).
Is there anyone coding my project?
My sample data is constructed the structure type of Matlab.
My data description is as follows;
The contents of sample data are ship’s data(date, time, latitude, longitude, course, speed) according to each ship id(MMSI).
The time interval of ship’s location is 2~35 second(less than 180 second).
So, that’s why ship’s data was interpolated per second.
The interpolated data was changed to bigger size than the original data.
I shared you my interpolated data, matlab function and powerpoint on google drive.

The CPA means as follows;
An estimated point in which the distance between two ships. abbreviated CPA(Closest Point of Approach).
The estimate is used to evaluate the risk of a collision of two ships.
I shared one video recording file for explanation of CPA concept on google drive.

You can see that as time goes by, CPA and TCPA changed on video file.
I have a matlab algorithm(function) about CPA. The algorithm was made from a journal.
I attatched an algorithm function about CPA.
My data is 250 ships.
Example
May 1st, 2014
If No.1 ship and No.2 ship in same date and time, I want to calculate DCPA, TCPA and range using my algorithm function.
And then, I want to select latitude and longitude for plotting location which is risk of collision of two ships.
(criterion lower than DCPA 0.15 nautical mile and lower than TCPA 3 minute).
...
No.1 and [url removed, login to view] should be calculated DCPA, TCPA and range.
And then, I want to select latitude and longitude for plotting location which is risk of collision of two ships.
No.2 and No.3 should be calculated DCPA, TCPA and range.
And then, I want to select latitude and longitude for plotting location which is risk of collision of two ships.
...
No.2 and [url removed, login to view] should be calculated DCPA, TCPA and range.
And then, I want to select latitude and longitude for plotting location which is risk of collision of two ships.
...
[url removed, login to view] and [url removed, login to view] should be calculated DCPA, TCPA and range.
And then, I want to select latitude and longitude for plotting location which is risk of collision of two ships.
May 2nd, 2014 => same procedure.
May 3rd, 2014 => same procedure.
...
last day
My purpose of this study is to find where is risk area of collision of two ships.
I have big data which is bigger than 4.0GB.
So, please should be considered speed for execution.
Is there anyone coding my project?
