CumProd

Return the cumulative product of matrix/vector elements, including those along the given axis.

vector vector::CumProd();

vector matrix::CumProd();

matrix matrix::CumProd(
const int axis // axis
);

Parameters

axis

[in] Axis. 0 — horizontal axis for each column (i.e., over the rows), 1 — vertical axis for each row (i.e. over the columns)

Return Value

Cumulative product of the elements along the given axis.

Example

   matrix matrix_a={{10,3,2},{1,8,12},{6,5,4},{7,11,9}};
   Print("matrix_a\n",matrix_a);

   matrix cols_cumprod=matrix_a.CumProd(0);
   matrix rows_cumprod=matrix_a.CumProd(1);
   vector cumprod_values=matrix_a.CumProd();

   Print("cols_cumprod\n",cols_cumprod);
   Print("rows_cumprod\n",rows_cumprod);
   Print("cumprod values  ",cumprod_values);
