a. Low in value, rank, or social status: "I preferred the condition of the meanest reptile to my own" (Frederick Douglass). b. Common or poor in appearance; shabby: "The rowhouses had been darkened by the rain and looked meaner and grimmer than ever" (Anne Tyler). 5. Slang a. ...
Different gestures (手势) mean different things in different countries. Sometimes a gesture that is polite in one country is not polite in another and should not be used. Different meanings of gestures can also cause problems in understanding what another person is trying to say. A gesture that...
mean(A,1) computes the mean of the elements in each column of A and returns a 1-by-n row vector. mean(A,2) computes the mean of the elements in each row of A and returns an m-by-1 column vector. mean returns A when dim is greater than ndims(A) or when size(A,dim) is 1...
Compute the mean and standard deviation of each row in a data matrixRaphael Gottardo
mean(A,1) computes the mean of the elements in each column of A and returns a 1-by-n row vector. mean(A,2) computes the mean of the elements in each row of A and returns an m-by-1 column vector. mean returns A when dim is greater than ndims(A) or when size(A,dim) is 1...

Find the mean of the elements in eachX(i,:,:)slice by specifying dimensions 2 and 3 as the operating dimensions. yrow = nanmean(X,[2 3]) yrow =2×114.5385 16.7692 For example,yrow(2)is the mean of the non-NaNelements inX(2,:,:). ...
mean(A,dim)A是待处理的输入矩阵 dim是要求平均的维 不输入dim时，直接调用 mean(A)有两种情况 1，当A是数列的时候，也就是大小是 nx1 或者 1xn的时候 mean(A)返回数列的平均值，一个标量 2，当A是矩阵的时候，也就是大小是nxm的时候，（m，n都大于1）这是时候dim默认取1，也就是mean(A...

IfAis a matrix, thenwmean(A,weights)returns a row vector containing the weighted mean of each column. IfAis a multidimensional array, thenwmean(A,weights)operates along the first array dimension whose size does not equal 1, treating the elements as vectors. This dimension ...
