Block Category: Arithmetic

Inputs: Real or complex scalars, vectors, or matrices. When vector and matrix inputs are of unequal lengths, the summingJunction block defines the output vector or matrix to be the maximum composite size of all the incoming vectors or matrices and extends all other incoming vectors and matrices to match the length of the longest incoming vector or matrix, by padding each of them with the requisite number of 0s.

Description: The summingJunction block generates the sum of two signed input signals. You can toggle the sign by pressing CTRL+right-click over the connector.
