Operators

!

! is a operator for elementwise logical operation (not).

!=

!= compares elementwise. If the elements are not equal 1 is returned otherwise 0.

#

# evaluates all arguments as vectors and combines them into a single vector.

%

% is a operator for modulo division of arrays of matrices.

&&

&& is an operator for elementwise logical operation (and). If the condition is false 0 is returned, otherwise 1.

'

' transposes rows and columns of an array. This operator is equal to the function trans.

*

* computes the matrix multiplication of arrays.

+

+ is a operator for addition of arrays.

-

- is a operator for subtraction of arrays.

.*

.* is a operator for elementwise multiplication of arrays.

/

/ is a operator for elementwise division of arrays.

/**/

/* */ is a operator to allow comments in macros and datafiles. All text between /* and */ is ignored.

//

// is a operator to allow comments in macros and datafiles. All text after this operator is ignored. The Operator // is equvivalent to ;.

:

: generates additive sequences in ascending or descending order.

;

; is a operator to allow comments in macros and datafiles. All text after this operator is ignored. The Operator // is equvivalent to ;.

<

< is a operator for elementwise comparison of arrays (smaller). If the condition is false 0 is returned, otherwise 1.

<=

<= is a operator for elementwise comparison of arrays (smaller or equal). If the condition is false 0 is returned, otherwise 1.

<>

<> compares elementwise. If the elements are not equal 1 is returned otherwise 0.

=

= is a operator of assignment for arrays. if the left argument already exists, it will be overwritten. Otherwise it is created. The left side is always an exact copy of the right object.

==

== compares elementwise. If the elements are equal 1 is returned otherwise 0.

>

> is a operator for elementwise comparison of arrays (greater). If the condition is false 0 is returned, otherwise 1.

>=

>= is a operator for elementwise comparison of arrays (greater or equal). If the condition is false 0 is returned, otherwise 1.

[]

[] gives a subarray of an array.

^

^ is a operator for elementwise exponantiation of arrays.

_

this operator evaluates the following string as function or macro name.

{}

{} gives an element of a list.

|

| combines arrays rowwise.

||

|| is a operator for the logical operation or.

~

~ combines arrays columnwise.
