MATLAB dot product

dot( ) command or function gives the dot or scalar product of vectors or matrices or arrays, after reading this MATLAB dot product topic, you will know the theory and examples.

---

Syntax:

dot(a,b)

• a and b are two vectors.

Example: To find the dot product of two vectors.

Output:
A =

3  20  34

B =

13  2  3

ans =

181
Explanation:

the dot product of vectors A and B as A.B gives output 3*13+20*2+34*3 = 181.

Example: To find the dot product of two matrices.
Output:






A =

3   20  34
2   3   4
1   2   3


B =

13  2   3
3   4   5
2   6   8


ans =

47  64  146
Explanation:

47, 64 and 146 are the dot product value of the first, second and third corresponding columns of the matrices A and B.
