For more information on indexing methods, refer to the rtable_indexing help page. For more information on the Array constructor and the Array data structure, refer to the Array help page. The Array constructor supports other syntaxes. For example, the following is a simple three-dimensional Array.Ī ≔ Array 1. Since this method is relative, you can access the end of the array by entering − 1.Īrrays can have more than one or two dimensions. Round bracket indexing normalizes the dimensions to begin at 1. Square bracket notation respects the actual index of an Array, even when the index does not start at 1. To access entries in an Array, use either square bracket or round bracket notation. Standard Array constructor arguments are:Įxpression sequences of ranges - Specify the indices for each dimensionĪ ≔ Array 1. To define an Array, use the Array constructor. Each element has an index that you can use to access it. įor more information on sets and lists, refer to the set help page.Ĭonceptually, the Array data structure is a generalized list. Solve x − y 2 = −2, x + y = 0įor more information, see Solving Equations and Inequations. Some commands accept a list (or set) of expressions.įor example, you can solve a list (or set) of equations using the context panel or the solve command. Note: Lists preserve both the order and repetition of elements.įor more information, see Accessing Elements. įor more information on sets, refer to the set help page.Ī list is an expression sequence enclosed in brackets ( ). Note: The union operator is available in 1-D Math input as union. To perform mathematical set operations, use the set data structure.Ģ, 6, 5, 1 ⋃ 2, 8, 6, 7ġ, 2, 5, 6, 7, 8 Repeated elements are stored only once.Ĭ, a, a, a, b, c, a Note: This syntax is valid for most data structures.Ī set is an expression sequence enclosed in curly braces ( ).Ī Maple set has the basic properties of a mathematical set.Įach element is unique. You can select multiple expressions by specifying a range using the range operator (. Using negative integers, you can select an expression from the end of a sequence. S := 2, y, sin x 2, I :Įnter the sequence name followed by the position of the expression enclosed in brackets( ). It is a group of expressions separated by commas. The fundamental Maple data structure is the expression sequence. This section describes the key data structures: For more information on expressions, refer to the Maple Help System. Working with Maple Expressions - Tools for manipulating and controlling the evaluation of expressionsĬonstants, data structures, mathematical expressions, and other objects are Maple expressions. Ĭreating and Using Data Structures - How to define and use basic data structures For information on additional Maple programming concepts, such as looping, conditional execution, and procedures, see Basic Programming. Many of the commands described in this chapter are useful for programming. This chapter provides basic information on using Maple expressions, including an overview of the basic data structures.
