matlab 的 ln 函数ln 函数是指自然对数函数(natural logarithm function),用来求以 e (自然常数)为底的对数。用matlab 实现自然对数函数,可以使用 log 函数来完成。在 matlab 中, log 函数默认为以 e 为底的对数函数,即自然对数函数。例如,输入 log(10),得到的结果是 2.3026,表示以 e 为底的对数 log(10)...

Y= log(X)returns the natural logarithmln(x)of each element in arrayX. Thelogfunction’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally. For negative and complex numbersz = u + i*w, the complex logarithmlog(z)returns ...

编写sinc(x)=sin(x)/x的MATLAB函数 单个标量的Sinc函数: 对于要为标量输入运行的函数的一些调整包括:对于间隔之外的普通情况,将输出y设置为零。必须这样做,因为函数需要初始化并返回输出。另外,if-statement不需要在它们的末尾使用MATLAB中的semi-colons。 disp(sinc3(2));function y = sinc3(x)if x < 0 ...
【机器学习】代价函数(cost function) 注:代价函数(有的地方也叫损失函数,Loss Function)在机器学习中的每一种算法中都很重要,因为训练模型的过程就是优化代价函数的过程,代价函数对每个参数的偏导数就是梯度下降中提到的梯度,防止过拟合时添加的正则化项也是加在代价函数后面的。在学习相关算法的过程中,对代价函数...
