com.mathworks.extern.java.MWCellArray Class

Namespace: com.mathworks.extern.java

Java class to manage MATLAB cell arrays

Description

Declaration

public class MWCellArray extends MWArray implements java.io.Serializable

MWCellArray class manages a native MATLAB^® cell array. This class does not depend on MATLAB Runtime and should only be used in a Java^® RMI based application where the client machine does not have MATLAB Runtime installed.

Creation

Constructors

MWCellArray()

Creates an empty cell array.

MWCellArray(int[] inDims)

Constructs a new cell array with the specified dimensions.

MWCellArray(int rows, int cols)

Constructs a new cell matrix with the specified number of rows and columns.

Properties

Public Properties

No public properties.

Methods

Public Methods

toString	public java.lang.String toString() This method returns a string representation of the array. Overrides: toString in class MWArray Returns: None
equals	public boolean equals(java.lang.Object obj) Returns true if the input Object is of type MWCellArray and has equal elements. For the element value comparison, it depends on the implementation of equals for objects referred to by individual elements. Overrides: equals in class MWArray Returns: Return true if input object is same as this. Else returns false.

Examples

Create an Empty Cell Array

MWCellArray C = new MWCellArray();
      System.out.println("C = " + C.toString());

When run, the example displays this output:

  C = []

Create a Cell Matrix with Rows and Columns

public MWCellArray(int rows,
                   int cols)

Constructs a new cell matrix with the specified number of rows and columns.

Parameters

• rows—Number of rows. Number of rows must be non-negative.

• cols—Number of columns. Number of columns must be non-negative.

Throws

• java.lang.NegativeArraySizeException—A negative row or column size is supplied.

Create Cell Array with Specified Dimensions

public MWCellArray(int[] inDims)

Constructs a new cell array with the specified dimensions.

Parameters

• inDims—Array of dimension sizes. Each dimension size must be non-negative.

Throws

• java.lang.NegativeArraySizeException—A negative dimension size is supplied.

Example

int[] cdims = {2, 3};
     MWCellArray C = new MWCellArray(cdims);

     Integer[] val = new Integer[6];
     for (int i = 0; i < 6; i++)
        val[i] = new Integer(i * 15);

     for (int i = 0; i < 2; i++)
        for (int j = 0; j < 3; j++)
           {
           int[] idx = {i+1, j+1};
           C.set(idx, val[j + (i * 3)]);
           }

     System.out.println("C = " + C.toString());

When run, the example display this output:

 C = 2x3 cell array
