  • Theee.Array.identity(size) method creates a 2D identity matrix of a specified size.

  • Thesize argument is an integer that determines the length of each axis of the matrix.

  • The method returns an Earth Engine Array.

  • Examples demonstrate how to useee.Array.identity in JavaScript and Python, showing the output for various sizes including 0, 1, 2, and 3.

 Creates a 2D identity matrix of the given size.

ee.Array.identity(size)Array
ArgumentTypeDetails
sizeIntegerThe length of each axis.

Examples

Code Editor (JavaScript)

// []print(ee.Array.identity(0));// [[1]]print(ee.Array.identity(1));// [[1,0],//  [0,1]]print(ee.Array.identity(2));// [[1,0,0],//  [0,1,0],//  [0,0,1]]print(ee.Array.identity(3));
