sudoku solver game in matlab...very interesting to play

For inverting a matrix, Gauss-Jordan elimination is about as efficient as any other method. For solving sets of linear equations, Gauss-Jordan elimination produces both the solution of the equations for one or more right-hand side vectors b, and also the matrix inverse A(-1). However, its principal weaknesses are (i) that it requires all the right-hand sides to be stored and manipulated at the same time, and (ii) that when the inverse matrix is not desired, Gauss-Jordan is three times slower than the best alternative technique for solving a single linear set.

rake接收机仿真，Rake接收机是一种能分离多径信号并有效合并多径信号能量的最终接收机。瑞克接收的过程相当于用一个钉耙将各个多径信号“耙”出来，然后加以收集。(rake receiver simulation, Rake receiver is a multipath signals can be separated and the effective integration of multi-path signal energy of the final receiver. Rick received the equivalent of using a rake to process each multipath signal " rake" out, and then collecting them.)
