Description: 最小平方近似法 (least-squares approximation) 是用來求出一組離散 (discrete) 數據點的近似函數 (approximating function)，作實驗所得的數據亦常使用最小平方近似法來達成曲線密合 (curve fitting)。以下所介紹的最小平方近似法是使用多項式作為近似函數，除了多項式之外，指數、對數方程式亦可作為近似函數。關於最小平方近似法的計算原理，請參閱市面上的數值分析書籍-least square approximation (least-squares approximation) to get a group of discrete (discrete) data point to the approximate function (approximating function), the experimental data are often using the least square approximation to reach a secret curve (curve fitting) . Outlined below are the least square approximation is used as a polynomial approximation functions, in addition to polynomials, the index several right formula may be used as a similar function. On the smallest square approximation calculation principles, please refer to the numerical analysis of the market books Platform: |

Description: 多项式曲线拟合 任意介数 Purpose - Least-squares curve fit of arbitrary order
working in C++ Builder 2007 as a template class,
using vector<FloatType> parameters.
Added a method to handle some EMathError exceptions.
If do NOT want to use this just call PolyFit2 directly.
usage: Call PolyFit by something like this.
CPolyFit<double> PolyFitObj
double correlation_coefficiant = PolyFitObj.PolyFit(X, Y, A)
where X and Y are vectors of doubles which must have the same size and
A is a vector of doubles which must be the same size as the number of
coefficients required.
returns: The correlation coefficient or -1 on failure.
produces: A vector (A) which holds the coefficients.-Polynomial curve fitting the number of arbitrary referral Purpose- Least-squares curve fit of arbitrary order working in C++ Builder 2007 as a template class, using vector Platform: |

Description: At SRRC, a precision output current monitoring
system is installed to monitor the output performance of
all the booster/storage ring power supplies. Accurate DC
current transformers (DCCTs) are attached to the output
terminal of every power supply system. Each
transformer’ s gain/offset are carefully calibrated against
high precision current source and approximated using
high-order polynomial curve fitting. The output of each
DCCT is connected to multi-channels data logger for realtime
data collection, the collected data are calibrated
using the interpolated DCCT gain/offset value. A PC
station is set up to serve as host to store the current output
for real-time monitoring. This monitoring system provide
a precise real-time database for rapid fault diagnosing
whenever there is malfunction of the beam operation Platform: |
