prod
Product of array elements
Syntax
Description
returns
the product of the array elements of B
= prod(A
)A
.
If
A
is a vector, thenprod(A)
returns the product of the elements.If
A
is a nonempty matrix, thenprod(A)
treats the columns ofA
as vectors and returns a row vector of the products of each column.If
A
is an empty 0-by-0 matrix,prod(A)
returns1
.If
A
is a multidimensional array, thenprod(A)
acts along the first nonsingleton dimension and returns an array of products. The size of this dimension reduces to1
while the sizes of all other dimensions remain the same.
prod
computes and returns B
as single
when
the input, A
, is single
. For
all other numeric and logical data types, prod
computes
and returns B
as double
.
B = prod(
computes the product of all elements of A
,'all'
)A
. This syntax is
valid for MATLAB® versions R2018b and later.
