Description
B = prod(A)
returns the products along different dimensions of an array.
If A
is a vector, prod(A)
returns the product of the elements.
If A
is a matrix, prod(A)
treats the columns of A
as vectors, returning a row vector of the products of each column.
If A
is a multidimensional array, prod(A)
treats the values along the first non-singleton dimension as vectors, returning an array of row vectors.
B = prod(A,dim)
takes the products along the dimension of A
specified by scalar dim
.
Examples
