Hi,
The error you are encountering when calling "toString()" on a "MWNumericArray" object in your Java code is due to the way the "MWNumericArray" class handles multidimensional arrays. To avoid this error and correctly display the contents of your array, you can iterate over the elements of the array and build a string representation manually. Here's how you can modify your code to achieve this:
import com.mathworks.toolbox.javabuilder.*;
public class MWArrayError {
public static void main(String[] args) {
double[][] AData = {{ 1, 2, 3, 4, 5, 6},
{ 7, 8 , 9, 10, 11, 12},
{13, 14, 15, 16, 17, 18}};
MWNumericArray A = new MWNumericArray(AData, MWClassID.SINGLE);
StringBuilder sb = new StringBuilder();
sb.append("Array A = \n");
for (int i = 1; i <= A.numberOfElements(); i++) {
sb.append(A.get(i) + " ");
if (i % A.getDimensions()[0] == 0) {
sb.append("\n");
}
}
System.out.println(sb.toString());
}
}
In this modified code snippet, we create a "StringBuilder" to construct the string representation of the array manually. By iterating over the elements of the "MWNumericArray" and appending them to the "StringBuilder", we can avoid the error caused by the implicit call to "toString()" on a multidimensional array. This approach allows you to display the contents of your array in a readable format without encountering the runtime exception.
Hope it helps.
