Example Matrix ref 016

 

 

Description

This examples show the shorthand form of Matrix reference through the bracket [] operators. In this example, the Matrix value is referenced by using its index. The ref function is used either with the Matrix Name or the Matrix' Object ID.

 

Details

Define a Matrix containing various fruit names:

(define Fruits #(mat| "apple" "orange" "lemon")) Returns: #<Matrix 123456>

Define another Matrix.

(setq Food (new Matrix: 2 2 2 "apple" "orange" "lemon" "Pair")) Returns: #<Matrix 234567>

Accesses the Matrix value with index 0.

Fruits [0] Returns: apple

Accesses the Matrix value with index 1.

Food [1] Returns: orange

Accesses the Matrix value with index [1 0].

Food [1 0] Returns: lemon

Instead of the Matrix name, the object ID may be used to access the Matrix values

#<Matrix 123456>[0] Returns: apple

Accesses the Matrix value with index 1.

#<Matrix 123456>[1] Returns: orange

Accesses the Matrix value with index 2.

#<Matrix 234567>[1] Returns: orange

Notes and Hints

The ref function can be used for all of the specialized Matrix types: Number Matrices. An element in a Matrix can optionally be referenced with the [] operator. The brackets must contain a valid integer index to the specified Matrix element.
