    Modifier and Type Method Description
    static int[][][] eraseDuplicates​(int[][][] data)
    erase duplicates in a array of matrices the input matrix stays unchanged
    static int[][] eraseEmptySpace​(int[][] data)
    erase rows and columns that only exist of 0
    static int[][] horizontalInverse​(int[][] data)
    inverse the matrix horizontally it makes a copy, the input matrix stays unchanged
    static boolean isEqual​(int[][] data1, int[][] data2)
    check if 2 matrices are equal assuming they have the same size
    static void main​(java.lang.String[] args)  
    static int[][] makeBigger​(int[][] data, int size)
    expands a smaller than size*size matrix to a size*size matrix it makes a copy, the input matrix stays unchanged assuming that the input is smaller than size!!
    static void makeDatabase()
    make the database, created of the basicDatabase
    static int[][] moveToAbove​(int[][] data)
    move matrix to the left above corner doesn't make a copy!
    static int[][] rotate​(int[][] data, int rotation)
    rotate the matrix x amount of times over 90 degrees (assume that the matrix is a square!) it doesn't make a copy, so the return matrix doesn't have to be used
    static int[][] verticalInverse​(int[][] data)
    inverse the matrix vertically it makes a copy, the input matrix stays unchanged
