How To Change Matrix Value In Matlab

After reading the MATLAB Variable as Scalar, Vector, or Matrix topic, you will understand how to create a variable equally a Scalar, Vector, and Matrix in MATLAB.

Variable in MATLAB can exist of post-obit types:

A variable (or array) with 1 element is called scalar.
A variable (or array) with one row or one cavalcade of elements chosen vector.
A variable (or array) with elements in rows and columns is called matrix.

MATLAB Variable equally a Scalar

Aim (1): To define variable x having chemical element two every bit a scalar.

Programme (1):

ten = 2

Output (1):

x = 2

MATLAB VIEW – Program (ane) and Output (1):

Type the post-obit code in the command window and see the result –

MATLAB – Variable every bit Vector

Aim (one): To ascertain variable x every bit a vector and the elements of x are given by x=(i, 22, 3).

Plan (i):

x = [1,22,iii]

Output (1):

ten = 1   22     iii

MATLAB VIEW – Plan (1) and Output (1):

Type the post-obit lawmaking in the command window and encounter the result –

MATLAB – Variable as Matrix

Aim (1): To define variable x as a matrix and the elements of x are given by: x=(1, 22, 3, two, 34, 4, 12, 2, 4).

Program (1):

10 = [1,22,3;two,34,iv;12,ii,4]

Output (i):

x = 1   22     3 2   34     4 12   2     4

MATLAB VIEW – Program (1) and Output (1):

Type the post-obit code in the command window and see the result–

MATLAB – Proper commands for managing variables

Commands like clear, who and whos, that tin can be used to eliminate variables or to obtain information about variables that accept been created. When these commands typed in the Command Window and the Enter key is pressed, either they provide information, or they perform a task as specified below.

MATLAB – who command

who displays a listing of the variables currently in the memory.

MATLAB VIEW – to show who command execution

Earlier executing who command, variables are listed in Workspace as shown below

After executing who control, variables name displayed in the command window equally shown below

MATLABwhos control

whos displays a listing of the variables currently in the retention and their sizes together with information about their bytes and form.

MATLAB VIEW – to show whos command execution

Earlier executing whos command, variables are listed in Workspace equally shown below

After executing the whos command, variables name, size, bytes, class, attributes displayed in the control window as shown below

MATLABarticulate control

In MATLAB, clear command clears all the variables of the workspace.

MATLAB VIEW – to bear witness clear command execution

Before executing the articulate command, variables are listed in Workspace as shown beneath

Afterwards executing theclear command, variables gets cleared from the Workspace as shown below
