Background
I have no conflict of interest with the company MatLab.
MatLab is a contraction of the words Matrix Laboratory. It is a simple programming language,
not compilable,
fast and universal. It is cross platform (Mac, PC,
Linux) and there is a large community of users who use it and support it through worldwide.
There are many online references as well as user forums. The helping documentation included in the software is often enough as it is detailed and full of examples. We will explain how to access it.
Learning MatLab is faster than other programming languages such as C++ or JAVA.
Because remember that radiologists are not programmers !
Beware the MatLab language works only on the non free software provided by MatLab (http://www.mathworks.com).
After installing the software open it.
The top menu is similar to most programs.
Fig. 1: The program is as follows.
The Current Directory is the directory where your files are contained such as DICOM images,
data,
etc.. The Command Window is the space where you type the command lines that perform actions. Workspace is a working memory window displaying the names of variables containing the values generated by the program, size and content type of theses variables.
Note that the working memory is cleared when you close the program. The history window lists all of your past actions.
To start, you must first be placed in your working folder in the left window by clicking the double arrow <<. This contains the files you want to process. We will then ask MatLab to calculate a little bit to get familiar with its use.
From that moment,
you can call help typing DOC in the command window.
