B = cumprod(A) B = cumprod(A,dim)
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.
cumprod(1:5) = [1 2 6 24 120]
A = [1 2 3; 4 5 6];
disp(cumprod(A))
1 2 3
4 10 18
disp(cumprod(A,2))
1 2 6
4 20 120
cumsum Cumulative sum
prod Product of array elements
sum Sum of array elements
