Practical examples of basic methods for data analysis. It is performed in the format of Matlab reports. It collects examples of forecasting, linear and logistic regression, model selection and useful utilities.
||An introduction to the MatLab programming, the most useful codes
How to write Matlab codes
Devoted to C++ and VS programmers
- Matlab is very simple. There are no projects, no compilations and no libraries.
- There are command window, m-code window, path list and help.
- If you want to use a toolbox function, just use the function name in your code.
- There are no name collisions. The old name just dies when reloaded. Remember this pity fact.
- And keep the path list (see the main menu) up to date.
- Please search the help before making an algorithm. You will save lot of time.
- Then please search internet (special-purpose cites and wikipedia are highly recommended). There are the other researchers who make code, too.
- Do not afraid of using complicated algorithms. Often classification, scaling, regression, optimization is no more than one line of the code. It is not expensive.
- Your function help must be bright.
- The first line shortly explains the purpose of the function.
- The second one may name the function with in-out arguments.
- The next describes variants of usage or arguments formats.
And the example is essential. One can run your function using your help example.
- Make short examples of what you are doing and keep it to the future.
- Store useful functions in a repository. And comment them well.
- If you are making a large project, think how to organize functions in a proper way.
- Study all data structures of Matlab. There are plenty.
- Avoid ‘for’ when possible. Say, to multilply each column of a matrix A by constants x is A*diag(x), there is no ‘for’.
- To be continued. Good luck!
