liftingnodeform

欧拉向后差分格式的程序文件，可直接调用，在科学计算中有很重要的应用.(Euler backward difference scheme of program files can be called directly,which have important applications in scientific computing.)

说明：  c++编程bp神经网络，用c++语言编写的bp神经网络(C++ programming bp neural network, bp neural network written in c++ language.)

计算二维非问题油内热源问题导热，可以参考学习(Calculation of two-dimensional non thermal problems in oil heat conduction, you can refer to the study)

说明：  常用的matlab代码，非线性方程组求解，基本可以满足大学和研究生常用代码(Common Mathematical Codes)

说明：  一般的最小二乘通常是一次拿到全部的数据， 对所有数据进行统一优化计算得到模型系数。递推最小二乘是以一种递推的方式计算最小二乘，每次使用最新的测量值，来不断更新模型系数。(General least squares usually get all the data at one time, and perform unified optimization calculations on all the data to get the model coefficients. Recursive least squares is to calculate the least squares in a recursive way, each time the latest measured value is used to continuously update the model coefficients.)

说明：  含随机出题（四则运算）及其迭代程序、返回数组中最大子数组和及其迭代程序等。(Software class operations, including four operations and iterative procedure, returns an array of sub-arrays and the largest and Iterative procedures)

该程序完成了十进制数（包括小数）到二进制单精度浮点数的转换(The program completed a decimal number (including decimals) to single-precision floating-point binary conversion)

ista算法，用于最优化求解,迭代收敛，实用小程序(ista algorithm, for the most optimtical problem)
