The + Function: Conjugate, Plus
Monadic (One-Argument) Form: Conjugate +B
The conjugate function does not change the argument. The argument can be a
numeric scalar, vector, or other array, and the shape of the result is the same as that
of the argument:
If 6 is an array, the function is extended to each of the elements of €3. The shape of
the resullt is the shape of 6:
Bt.. 2 3 p "'3 "'2 ... 1. 0 1. 2
H
I.. ...,
3 2 .- 3.
0 1. 2
.I -2 *- 1
0 :I. 2
+ B
- ..
Dyadic (Two-Argument) Form: Plus A+B
The plus function results in the sum of the two arguments. The arguments can be
numeric scalars, vectors, or other arrays. Arguments must be the same shape, unless
one of the arguments is a scalar or single-element array. If the arguments have the
same shape, the result has the same shape as the arguments:
3 +. 3
3 + 2 I '7 3
2 4 6.t "3 * 13
3 , 1. :I. ." :I. -3+5 , j, 2 0 4
&
rs , '73
*.' 1. # 2
1 a , 2 3 .- :I. 1.

If one argument is a scalar or single-element array, the shape of the result is the same
as that of the other input argument. The single element is applied to every element
of the mulrielement array:
I
0
The - Function: Negation, Minus
Monadic (One-Argument) Form: Negation -B
The negation function changes the sign of the argument. The argument can be a
numeric scalar, vector, or other array. The shape of the result is the same as that of
the argument:
AC"1. -3
A
... :I. .'I 3
:I. 3
....
If the argument is an
array, the function is extended to each element of the array:
