误差分析的方法有多种，例如，威点逊（J. H. Wilkison）针对的计算机的浮点运算提出的“向后误差分析”，这是一种先验估计误差的方法，较以往的“向前误差分析”在矩阵运算的舍入误差估计上有较好的结果，以而使矩阵的误差分析获得了突破性的进展，使不少用向前误差分析难于判定可靠性的数值方法获得新的进展。-error analysis by a number of means, for example, Granville point Morrison (J. H. Wilkison), referring to a computer"s floating-point operations "backward error analysis," This is a priori estimation error method, compared to the previous "Forward Error Analysis" in the matrix computation Rounding error a better estimate on the results of a matrix so the error analysis of a breakthrough in the progress, many with forward error analysis difficult to determine the reliability of numerical methods to achieve new progress.

DTMF（Dual Tone Multi Frequency）Recognition Algorithm
Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.
While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for
