Cumulative product



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.
