正确的MATLAB语句应该是这样的：matlab p = 0.2;P = [p, 1-p];inf1 = -P.*log2(P);inf1 = sum(inf1);这里使用了点乘（.*）来逐元素计算，并且添加了负号来符合熵的定义。最后，使用sum函数来计算总和。如果你想要计算二符号信源的熵，可以使用上述代码。确保你的MATLAB版本支持这些操作。
a=log(2);b=log(0.8);c=-b/a 运行后 c = -0.3219 其实就是这个关系：log a B=In(B)/In(a)

log(100,10)返回2.0（即log₁₀100）log(8,2)返回3.0（即log₂8）与log()相关的函数对比：log1p(x)用于计算ln(1+x)，当x趋近于0时比log(1+x)更精确 log2(x)直接计算以2为底的对数 log10(x)直接计算以10为底的对数 实际应用场景举例：1.复利计算时用log(目标金额/本金,1+年利率)2.计算...
Log Plot Using thesemilogx()Function in MATLAB If you want to plot the variables on the x-axis of base 10 log scale and y-axis of linear scale. You can use thesemilogx()function. See the below code. a=1:100;b=2*a;lg=semilogx(a,b)grid on axis tight ...
这是不同于R13和早期版本。输入数据A可能是double或者single数据类型。以上摘自《matlab百科全书》参考资料：http://wiki.ilovematlab.cn/doc-view-152.html 功能是对矩阵求对数。【使用方法】格式1：L = logm(A)求A的主要矩阵对数，是expm(A)的逆运算。对任何一个虚部严格在...
