    The eye function in MATLAB is used to create an identity matrix. An identity matrix is a square matrix with ones on the main diagonal and zeros elsewhere.

    Example

    I = eye(4)
    % Output:
    % I =
    % 1 0 0 0
    % 0 1 0 0
    % 0 0 1 0
    % 0 0 0 1
    Cóipeáilte!

    Creating Rectangular Identity Matrix

    You can also create a rectangular identity matrix by specifying the number of rows and columns.

    I = eye(2,3)
    % Output:
    % I =
    % 1 0 0
    % 0 1 0
    Cóipeáilte!

    Specifying Data Type

    The eye function allows you to specify the data type of the identity matrix.

    I = eye(3, 'uint32')
    % Output:
    % I =
    % 1 0 0
    % 0 1 0
    % 0 0 1
    Cóipeáilte!

    Using Prototype Array

    You can create an identity matrix that has the same data type, sparsity, and complexity as an existing array.

    p = [1+2i, 3i];
    I = eye(2, 'like', p)
    % Output:
    % I =
    % 1.0000 + 0.0000i 0.0000 + 0.0000i
    % 0.0000 + 0.0000i 1.0000 + 0.0000i
    Cóipeáilte!

    Note: The eye function is versatile and supports various data types and sizes, making it useful for initializing matrices in different contexts.
