Guidelines for Working with MWArray Classes

The a1, a2,anda3 arrays constructed all contain a 2-by-14 MATLAB char

array. The column count of the array is equal to the largest string length in

the input array. Rows with fewer characters than the maximum are

Null

padded. Arrays with larger numbers of dimensions are handled similarly.

This behavior parallels the way that

MWNumericArray and MWLogicalArray

handle jagged arrays.

Using Static Factory Methods for Constructing MWCharArrays

The following table lists the factory methods of MWCharArray.

Factor y Method Usage

newInstance(int[])

New char array. Values are initialized to Null.

newInstance(int[]

Object)

New char array. Values are initialized with

supported data.

These methods all return a new MWCharArray instance constructed from the

input informatio n . You can use these m ethods to construct a nd initialize

an array with supplied data, or to construct an a rray of a specified size and

initialize all values to zero. The main difference is that data is supplied to

the factory methods in one-dimensional arrays with the d ata arranged in

column-wise order. The input data array m ust be either a one-dimensional

array of

char, a one-dimensional array of java.lang.Character,orasingle

java.lang.String.

Rewriting Strings Using the newInstance Method. The following

examples rewrite the character string examples using

newInstance:

char[] x1 = {'A', ' ', 'S', 't', 'r', 'i', 'n', 'g'};

String x2 = "A String";

Character[] x3 =

{

new Character('A'),

new Character(' '),

new Character('S'),

new Character('t'),

new Character('r'),

new Character('i'),

new Character('n'),
