Scalar Operations of MATLAB Matrices

When you add, subtract, multiply, or divide a matrix by a number, this is calledscalar operation(Scalar operations).

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

Online Examples

Create a script file using 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 the file is run, 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
