资源描述 Design a program to implement the 1-D FFT algorithm. Input: a vector. Get the testing data in file ‘Project_2_test’. Output: a vector, which is the discrete Fourier transform of the input. For example: Input: 3 8 10 12 Output: 33.0000+0.0000i -7.0000+4.0000i -7.0000+0.0000i -7.0000-4.0000i Requirements:

应用背景Implement k-means clustering on a training data set  to predict classification values of a test data set.关键技术The experiment intended to classify test data values using the data   mining strategy known as k-means clustering.   The 6 variables in the training data are used to plot the data and   centroids are placed to locate clumps of the 255, classified training   data. Once located, a classification value can be assigned to the 100,   test data. 

对数回归方程 LogarithmRegress.cs 方程模型为 Y=a*LnX+b public override double[] buildFormula() 得到系数数组，存放顺序与模型系数相反，即该数组中系数的值依次是b,a。 public override double forecast(double x) 预测函数，根据模型得到预测结果。 public override double computeR2() 计算相关系数（决定系数），系数越接近1，数据越满足该模型。 -Logarithmic regression equation LogarithmRegress.cs equation model for Y = a* LnX+ Bpublic override double [] buildFormula () get coefficient array, the storage order and model coefficients contrary, that is, the array is followed by the value of coefficient b, a. public override double forecast (double x) prediction function, according to the results of model prediction. public override double computeR2 () calculated the correlation coefficient (determination coefficient), coefficient of the closer one, the data satisfy the model more.

一个通用的矩阵综合算法；能实现加、减、乘、转置以及初始化设置功能(大小和初值)。-A common matrix integrated algorithm to achieve add, subtract, multiply, transpose function, as well as initialization settings (the size and initial value).
