Matrix and array operations

MATLAB allows you to use a single arithmetic operator or function to manipulate all values ​​in a matrix

a + 10

MATLAB will execute the above statement and return the following results:

ans = 3×3
    11    13    15
    12    14    16
    17    18    20

sin(a)

MATLAB will execute the above statement and return the following results:

ans = 3×3
    0.8415    0.1411   -0.9589
    0.9093   -0.7568   -0.2794
    0.6570    0.9894   -0.5440

To transpose a matrix, use single quotes (')

a'

ans = 3×3
     1     2     7
     3     4     8
     5     6    10

Perform standard matrix multiplication using the * operator, which computes the inner product between rows and columns

p = a*inv(a)

p = 3×3
    1.0000         0         0
         0    1.0000         0
         0         0    1.0000
