toImagArray. This method returns an array containing a copy of the

The prototype for the

toImagArray method is

public Object toImagArray()

The array that is returned has the same dimensionality as the MATLAB array.

The elements of this array are converted according to default conversion rules.

Input Parameters

None

Example — Getting Complex Data with toImagArray

Using the same array as in the example for “getImag” on pag e 4-81, get and

display a copy of the imaginary part of that array:

double[][] x = (double[][]) A.toImagArray();

int[] dimA = A.getDimensions();

System.out.println("The imaginary part of matrix A is:");

for (int i = 0; i < dimA[0]; i++)

{

for (int j = 0; j < dimA[1]; j++)

System.out.print(" " + x[i][j]);

System.out.println();

}
