BIGSOM_f
Scalar or vector Addition/Soustraction
Block Screenshot
Description
This block performs addition or soustraction on its scalar or vector
inputs.The user can adjust the gain for each input with the parameter
Inputs ports signs/gain. The behavior of the block is summarized
in the following table :
Number of inputs Operation Remarks One y = k*u k is the
scalar value in Inputs ports signs/gain parameter. The block has
the behavior of a gain. Two or more y = k[1]*u1+k[2]*u2+...+k[n]*uN k
is the vector value write in Inputs ports signs/gain parameter. To
subtract an input ui, set a negative value in k[i].
Dialog box
- Inputs ports signs/gain Set sign and a gain for each inputs.
