About Creating Arrays and Tables
Creating Arrays
Vectors and matrices can be created in a number of ways:
Using the Matrices/Tables tab on the main Ribbon.
Using keyboard shortcuts
Importing data from a file
Defining a matrix using the index operator, a range and a formula relating the value of an array element to its indices
Using functions that generate special matrices. For example, the function identity returns an n × n matrix whose diagonal elements are set to 1's while the remaining elements are set to 0's.
Creating Tables
Tables can be created in one of two ways:
Using the Matrices/Tables tab on the main Ribbon.
Using keyboard shortcuts
Additional Information
You can assign a variable name to a matrix and use it in any calculation.
Arrays cannot contain empty elements. Insert a NaN in any array element for which you have no real value.
Defining elements individually or out of sequence may result in creating large matrices, or matrices with some elements set unexpectedly to 0.
