// Example 13-9: Two-dimensional array

// Set up dimensions
size(200,200);
int cols = width;
int rows = height;

// Declare 2D array
int[][] myArray = new int[cols][rows];

// Initialize 2D array values
for (int i = 0; i < cols; i ++ ) {
  for (int j = 0; j < rows; j ++ ) {
    myArray[i][j] = int(random(255));
  }
}

// Draw points
for (int i = 0; i < cols; i ++ ) {
  for (int j = 0; j < rows; j ++ ) {
    stroke(myArray[i][j]);
    point(i,j);
  }
}
