MATLAB - Scalar Operations of Matrices

Advertisements


When you add, subtract, multiply or divide a matrix by a number, this is called the scalar operation.

Scalar operations produce a new matrix with same number of rows and columns with each element of the original matrix added to, subtracted from, multiplied by or divided by the number.

Example

Create a script file with the following code:

a = [ 10 12 23 ; 14 8 6; 27 8 9];
b = 2;
c = a + b
d = a - b
e = a * b
f = a / b

When you run the file, it displays the following result:

c =
    12    14    25
    16    10     8
    29    10    11
d =
     8    10    21
    12     6     4
    25     6     7
e =
    20    24    46
    28    16    12
    54    16    18
f =
    5.0000    6.0000   11.5000
    7.0000    4.0000    3.0000
   13.5000    4.0000    4.5000
