该算法程序包含拉格朗日插值和样条插值等多个功能。(The algorithm contains multiple functions Lagrange interpolation and spline interpolation.)

解优化问题时常用的惩罚函数法，分为内点法和外点法两种，求解约束优化问题最优值。(Penalty function method, including interior point method and exterior point method, to solve the optimal value of constrained optimization problems.)

交织码通常表示为（M，N），分组长度L=MN，交织方式用M行N列的交织矩阵表示。一般，交织方式分为分组交织和卷积交织。分组交织的交织矩阵按列写入，按行读出；去交织矩阵按行写入按列读出。卷积交织的交织矩阵和去交织矩阵的写入与读出均按行进行。(Intertwined code is usually expressed as (M, N), the packet length L = MN, interwoven manner, said interwoven matrix with M rows and N columns. In general, interwoven into the packet interleaving and convolutional interleaving. Grouping of interwoven interwoven matrix column to write, to read de-interlacing matrix read out by column written by line by line. Convolutional interleaving interleaving matrix and de-interlacing matrix to write and read are OK.)
