MATLAB中log(1+double(f))是以几为底是不是默认以2为底还有这种写法2*log(1+double(f))上面的2是不是底的意思 谢谢

Matlab中 double(a(:,:,1))是什么意思 MATLAB中log(1+double(f))是以几为底是不是默认以2为底还有这种写法2*log(1+double(f))上面的2是不是底的意思 谢谢 matlab中-Ei(1,-log(x))什么意思? matlab中double* 的意思如题,double* pArr = (double*)mxGetPr(prhs[0]);这句中double*的意思. matlab 中如何将unit8转成double型 matlab中合并对数?如何实现log(a)-log(b)=log(a/b) matlab res = Columns 1 through 6[1x74 double] [1x5 double] [1x90 double] [1x198 double] [1x11 double] [1x70 double]Columns 7 through 12[1x2 double] [1x18 double] [1x129 double] [1x52 double] [1x6 double] [1x11 double]Columns 13 through 17[1x39 double c报错 invalid operands of types 'double' and 'double()(double)' to binary 'operator/'是怎么回事啊double mutual(double a,double b,double f){double y;y=(-(b*a+f*(1-a))*log(b*a+f*(1-a))-((1-b)*a+(1-f)*(1-a))*log((1-b)*a+(1-f)*(1-a))-a*(-b*log(b) matlab中imshow(log(abs(F)+1),[ ])最后一个方括号的数值如何设置 r(k)' =log(r(k)+1)怎么在matlab中编写 matlab中如何绘制4.4*x*(log(50/x) matlab如何定义double变量 matlab中cell元素个数问题得到一个1*1597的cell,格式大概是[43] [1*2double] [62] [33] [1*4double] [1*2double]等等.如何算出cell里一个元素的总数有多少,如[43] [62] [33],两个元素的总数有多少,如[1*2double] , 三 请求高人帮我解读下面这句MATLAB语句fx = conv2(double(im1),double(0.25* [-1 1; -1 1])) + conv2(double(im2),double(0.25*[-1 1; -1 1])); 尤其是double(0.25* [-1 1; -1 matlab中涉及复数运算是不是需要把数据类型转换为double类型 如何在matlab图像中从unit8转换成Double或single matlab中怎么把logical临行的矩阵转化为double类型 matlab中出现?Conversion to double from sym is not possible.
