MATLAB is a language used by engineers and scientists for computational mathematics. It is used for developing algorithms, analyzing them, and also for creating models and applications. MATLAB also helps in developing applications using by deploying applications, embedded devices, and also interpreting using Simulink. To get started with MATLAB there are some basic commands required which are simple and very user-friendly.

Different MATLAB Commands:

Clear – This command removes variables from the memory

Exist – This command checks for the existence of a variable

Clc – This command clears the command window

Global – This command declares a variable as global

Help – If you need to search for any help just write the keyword at command window and it displays your available options

Who – This command lists the current variable

Type – This command displays the contents of a file.

Pwd – This command displays the current directory.

Date – This command displays the current date

What – This command lists all the Matlab files in the current directory

Matrices and vectors command

x(:) – This command selects all the elements of x

x(j:end) – This command selects jth to end element of x

x(j,:) – This command selects all j row elements

x(:,j) – This command selects all j column elements

diag(x) – This command selects the diagonal elements of x

Eye – This creates an identity matrix

Ones – This creates the array of ones

Zeros – This creates the array of zeros

Dot- This command generates the dot product of two matrices, note that the columns and rows of matrix decide the resulting matrix creation

Cross – Synonymously this creates the cross product, helpful in vector operations when represented in the matrix form

Rank – This command provides the result to an important mathematical parameter of matrices called rank which is the quantification of the lowest order of non-zero determinant carrying sub-matrix in the parent matrix

Det – Determinant of the matrix is calculated using this command.

Inv – Execution of this command provides us the inverse of a matrix.

edit file – This command opens the selected filename in the editor window

Alt – This command displays the hotkeys

Using Function keys:

F1 – This command helps for highlighting the selected function

F5 – This command runs the code

F9 – This command runs the highlighted code

F10 – runs code line

F12 – This command inserts a break point

Using Shift key:

Shift + F5 – This command leaves the debugger

Using Control Key:

Ctrl + R – This command helps in commenting a line

Ctrl + N – This command opens a new script

Ctrl + w – This command closes a script window

The following commands are enough for starting using MATLAB. Other than that, as its an easy language, it is very easy to understand and makes coding
