Using Class Methods

Structure data S(1,1).f2 is 555

getData. This method returns a one-dimensional array containing a copy

of the data in the underlying MATLAB array. The

getData method of

MWStructArray ov erride s the getData method of class MWArray.

The prototype for the

getData method is

public Object getData()

getData

returns a one-dimensional array of e lements stored in column-wise

order. Before converting, a new array is derived by transforming the struct

array into a cell array such that an N-by-M-by-... struct array with P fields

is transformed into a P-by-N-by-M-by-... cell array. Each element in the

returned array is converted to a Java a rray when you call

MWArray.toArray()

on the corresponding cell.

Input Parameters

None

Example — Getting Structure Array Data with getData

Get the data stored in all field s an d in dices of MWStructArray object S:

int[] sdims = {1, 2};

String[] sfields = {"f1", "f2", "f3"};

MWStructArray S = new MWStructArray(sdims, sfields);

int count = S.numberOfElements() * S.numberOfFields();

// Initialize the structure.

Integer[] val = new Integer[6];

for (int i = 0; i < count; i++)

val[i] = new Integer((i+1) * 15);

// Use getData to get data from the structure.

System.out.println("Data read from structure array S: \n");
