How to calculate the product of the elements of a vector in Matlab and Octave

Use the prod() function to calculate the product of the elements of a vector in Matlab and Octave

prod(v)

The parameter v is the vector.

The prod() function multiplies the values of the vector elements and outputs the product.

Example

Define a vector

>> v=[1 2 3 4]
v =
1 2 3 4

Calculate the product of the elements of the vector using the prod(v) function

>> prod(v)
ans = 24

The product of the elements of the vector is equal to 24

$$ 1 \cdot 2 \cdot 3 \cdot 4 = 24 $$
