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].
