Fortran-Algorithms

对于交错网格上的WCNS格式进行精度测试（不带时间方向推进，仅测试空间精度）(test the order of accuracy of the WCNS scheme)

说明：  matlab的时频分析工具箱，含全部工具箱程序(Matlab time-frequency analysis toolbox, including all toolbox programs)

Fortran program which can be used to solve linear system

A tensor product (ranks 1 and 2) matlab app

基于matlab AR模型的最小二乘法实现参数辨识，加上Word配合理解，相信你理解的会更快的。(Matlab AR model based on the least squares method to achieve parameter identification, coupled with Word understanding, I believe you will understand faster.)

外国人写的卡尔曼滤波器算法的库，可以供大家参考，已经封装好了(kalman library)

C++实现的FFT，详细，简单，内含多个测试类(using C++ implements fft，including serials class)

最小二乘估值的SVD分解计算方法，本程序可将最小二乘估值问题转化为超定方程组的问题处理，且可用奇异值分解的方法计算最小二乘问题。(Least Squares Estimates of the SVD decomposition method, the valuation process can be transformed into squares overdetermined equations deal with the problem, and can be calculated singular value decomposition least squares problem.)

有限元NONSAP源程序，里面带有例子，大家可以参考。(Finite element NONSAP source, which with examples, we can refer to.)

说明：  给定四个数（1--13），判经过四则运算后能否得到结果24，若能，输出表达式。 (Given the number four (1- 13), after sub after four computing results can be 24, if the output expression.)
