y = a + b
where a
and b
are n
-dimensional arrays of numerical type. In the
first case, the two arguments are the same size, in which case, the
output y
is the same size as the inputs, and is the element-wise the sum
of a
and b
. In the second case, either a
or b
is a scalar,
in which case y
is the same size as the larger argument,
and is the sum of the scalar added to each element of the other argument.
The rules for manipulating types has changed in FreeMat 4.0. See typerules
for more details.
If a
is a scalar, then the output is computed via
On the other hand, if b
is a scalar, then the output is computed via
--> 3 + 8 ans = 11
Next, we add a scalar to a vector of values:
--> 3.1 + [2,4,5,6,7] ans = 5.1000 7.1000 8.1000 9.1000 10.1000
With complex values
--> a = 3 + 4*i a = 3.0000 + 4.0000i --> b = a + 2 b = 5.0000 + 4.0000i
Finally, the element-wise version:
--> a = [1,2;3,4] a = 1 2 3 4 --> b = [2,3;6,7] b = 2 3 6 7 --> c = a + b c = 3 5 9 11
