Matrix

The interface represents matrices in the form of a double-nested Array, where the outer array size equals the matrix’ column count. Each nested array represents a matrix column and its number of elements equals the matrix’ row count.

Array/Matrix	Node representing a 2x3 matrix (2 rows, 3 columns)
0 (Array/Vector)	The two element vector containing the first column.
1 (Array/Vector)	The two element vector containing the second column.
2 (Array/Vector)	The two element vector containing the third column.
