This blocks computes output y as sum of the elements of the input signal vector u:

y = u[1] + u[2] + ...;

Example:

   parameter:   nin = 3;

results in the following equations:

   y = u[1] + u[2] + u[3];

nin	Value: 1 Type: Integer Description: Number of inputs
k	Value: ones(nin) Type: Real[nin] Description: Optional: sum coefficients
