间断函数 meaning in English

discontinuous function

In the numerical calculation , the unknown function is approximated by the product of basic density function and polynomials
根据裂纹面上位移函数的分布特性，通过将位移间断函数表示为特征函数和一组多项式乘积的形式，为其建立了数值方法。
We call this method point - tree structure genetic programming algorithm ( ptgp ) . this algorithm has been applied into symbolic regression and parameter identification . the results show that ptgp is a good method
我们将这种算法应用到间断函数回归问题(符号回归问题)和间断参函数识别问题(偏微分方程反问题)中，测试结果表明，点树遗传程序设计算法能够有效的识别间断函数。
