MATLAB Tutorial
I decided to take the MatLab Tutorial to get a better understanding of the software. The tutorial is available in the MatLab webpage.

On-Ramp
MatLab Desktop
 * Command Window
 * Command History
 * Current Folder Browser
 * Workspace Browser

MatLab Fundamentals

1. Variables

doc. Documentation

format long, Displays all the content of a variable, the size depends on the type of the variable.

format short


 * MatLab variables are arrays
 * Multiple asigments are not allow in MatLab

2.Accesing Data

whos. Show the Workspace Browser in the Comand Window.

3. Creating a Vector

x = i:d:j
 * i, initial value
 * d, interval of numeric values
 * j, last value

4. Creating a Matrix
 * row separator, space | ;
 * colum separator, space | ,

matrix(r,c)

matrix(r,[i j]) | matrix(r,i:j)

matrix([i j], c) | matrix(i:j, c)

All array

matrix (r,:)

matrix (:,c)

Concatenate matrices

matrixes = [matrix;matrix]

Note
 * ; (semicolon) at the end of a comman line help to save computational time.
