2cumprod
Purpose Cumulative product
Syntax B = cumprod(A)
B = cumprod(A,dim)
cumprod
Description B = cumprod(A) returns the cumulative product along different dimensions of
an array.
If A is a vector, cumprod(A) returns a vector containing the cumulative product
of the elements of A.
If A is a matrix, cumprod(A) returns a matrix the same size as A containing the
cumulative products for each column of A.
If A is a multidimensional array, cumprod(A) works on the first nonsingleton
dimension.
B = cumprod(A,dim) returns the cumulative product of the elements along the
dimension of A specified by scalar dim. For example, cumprod(A,1) increments
the first (row) index, thus working along the rows of A.
Examples cumprod(1:5)
ans =
1 2 6 24 120
A = [1 2 3; 4 5 6];
cumprod(A)
ans =
1 2 3
4 10 18
cumprod(A,2)
ans =
1 2 6
4 20 120
