IMathElement

All Known Implementing Classes:

MathMatrix
```
public interface IMathMatrix
extends IMathElement
```
Specifies the Matrix object, consisting of child elements laid out in one or more rows and columns. It is important to note that matrices do not have built in delimiters. To place the matrix in the brackets you should use the delimiter object (IMathDelimiter). Null arguments can be used to create gaps in matrices.
```
Example:
  IMathMatrix matrix = new MathMatrix(2, 3);
 matrix.set_Item(0, 0, new MathematicalText("item.1.1"));
 
 
```
