Operator Function Syntax Explanation
++ Post
Increment
–– Post
Decrement
a++
Post Increment(a)
a––
Post Decrement(a)
Adds one (1) to a, in place.
Subtracts one (1) from a, in place.
^ Power a^b
Power(a,b)
Power(x)
– Minus –a
Minus(a)
! Not !a
Not(a)
* Multiply a*b
Multiply(a,b)
:* EMult a:*b
EMult(a,b)
/ Divide a/b
Divide(a,b)
Divide(x)
:/ EDiv a:/b
EDiv(a,b)
+ Add a+b
Add(a,b)
– Subtract a–b
Subtract(a,b)
|| Concat a||b
Concat(a,b)
|/ VConcat matrix1|/matrix2
VConcat(matrix1,
matrix2)
Raise a to exponent power b. With only
one argument, 2 is assumed as the
power, so Power(x) computes x 2 .
Reverses sign of a.
Logical Not. Maps nonzero (or true)
values to 0 (which means false). Maps 0
(or false) values to 1 (which means true).
Multiplies a by b.
Elementwise multiplication for matrices
a and b. (Each element in matrix a is
multiplied by each element in matrix b.)
Divide(a, b) divides a by b.
Divide(x) interprets the argument as a
denominator and implies 1 as the
numerator, yielding the reciprocal 1/x.
Elementwise division for matrices a and
b. (Each element in matrix a is divided
by each element in matrix b.)
Adds a and b.
Subtracts b from a.
Concatenates strings together and
horizontally concatenates matrices.
Vertically concatenate matrices. (Use ||
or Concat() to horizontally
concatenate matrices.)
