Octave Fuzzy Logic Toolkit: algebraic_sum

### Function Reference: `algebraic_sum`

Function File: retval = algebraic_sum (x, y)
Function File: retval = algebraic_sum (x, y)

Return the algebraic sum of the input. The algebraic sum of two real scalars x and y is: x + y - x * y

For one vector argument, apply the algebraic sum to all of elements of the vector. (The algebraic sum is associative.) For one two-dimensional matrix argument, return a vector of the algebraic sum of each column.

For two vectors or matrices of identical dimensions, or for one scalar and one vector or matrix argument, return the pairwise algebraic sum.
