Guidelines for Working with MWArray Classes

Here, each cell is initialized with a Java a rray, and default conversion rules

are used to create the MATLAB array for each cell.

Constructing an MWCellArray Containing Complex Arrays. The next

example creates a helper function that constructs a cell array containing a list

of complex

double arrays. The real and imaginary parts of each cell are passed

in the

re and im arrays, respectively. The new cell array has dimensions

1-by-

N,whereN is the leng th of the inp ut arrays, which must be the same.

MWCellArray createNumericCell(Object[] re, Object[] im)

throws MWException

{

if (re == null || im == null)

throw new MWException("Invalid input");

if (re.length != im.length)

throw new MWException(

"Input arrays must be the same length");

MWCellArray a = null;

MWNumericArray x = null;

try

{

a = new MWCellArray(1, re.length);

for (int k = 1; k <= re.length; k++)

{

x = new MWNumericArray(re[k-1], im[k-1],

MWClassID.DOUBLE);

a.set(k, x);

x.dispose();

x = null;

}

return a;

}

catch (Exception e)

{

if (a != null)

a.dispose();
