The "GEE! It s Simple" package illustrates Gaussian elimination with partial pivoting, which produces a factorization of P*A into the product L*U where P is a permutation matrix, and L and U are lower and upper triangular, respectively.
The functions in this package are accurate, but they are far slower than their MATLAB equivalents (x=A\b, [L,U,p]=lu(A), and so on). They are presented here merely to illustrate and educate. "Real" production code should use backslash and lu, not this package.

(1) 硬件電路中用P1.0~P1.7控制按鍵,其中P1.0~P1.3掃描行,P1.4~P1.7掃描列。
(2) 用P0.0~P0.7,P2.0~P2.7控制LED,其中P0.0~P0.7控制七段碼a,b,c,d,e,f,g,用P2.0~P2.7為數碼管位選信號。
(3) 用,P2.0~P2.2作為LCD的RS,R/W,E的控制信號。用P0.0~P0.7作為LCD的D0~D7的控制信號。
(4) 用P3.7口控制蜂鳴器(J2,J4斷開,J3短接)。
(5) 電路為12MHZ晶振頻率工作,起振電路中C1,C2均為30pf。
