prodc#

Purpose#

Computes the products of all elements in each column of a matrix.

Format#

y = prodc(x)#

Parameters:: x (NxK matrix) – data
Returns:: y (Kx1 matrix) – contains the products of all elements in each column of x.

Examples#

x = { 1 2 3,
      4 5 6,
      7 8 9 };

y = prodc(x);

The code above assigns y to be equal to:

     28
y =  80
    162

Remarks#

To find the products of the elements in each row of a matrix, transpose before applying prodc(). If x is complex, use the bookkeeping transpose (.').

To find the products of all of the elements in a matrix, use the vecr() function before applying prodc().
