测量氨水的气体浓度（由平均阻值和平均电压来表示），它受到环境湿度和加热电压的影响。(Measurement of ammonia gas concentration (from an average resistance and average voltage to that), it is affected by environmental humidity and the heating voltage.)

信噪比信噪比信噪比信噪比比信噪比比信噪比(snrsnrsnrsnr)

Crout s algorithm is used when the inversion of large matrices, say 1000X1000 is difficult. So Crout s algorithm uses LU decomposition method to get the same results as the inversion of Matrix.
