·M = mean(A,dim)returns the mean along dimensiondim. For example, ifAis a matrix, thenmean(A,2)is a column vector containing the mean of each row.(返回沿维度dim的平均值。例如,如果A是矩阵,那么mean(A,2)是包含每行平均值的列向量。) ·xlswrite(filename,A,sheet,xlRange)writes to the...

A=[1 3 4 5; 2 3 4 6;1 3 1 5]对矩阵A求平均,mean(A):如果是求平均的话,答案应该是: 1.3333 3.0000 3.0000 5.3333为什么我这显示的答案是: 4 9 9 16非常费解!请问有人碰到这种情况没有? 咋解决?>> A=[1 3 4 5; 2 3 4 6;1 3 1 5];>> B=mean(A)B =4 9 9 16>> C=mean(A...
9、the mean along the dimension DIM of X% rand产生的是0到1(不包括1)的随机数.matlab的rand函数生的是伪随机数,即由种子递推出来的,相同的种子,生成相同的随机数.matlab刚运行起来时,种子都为初始值,因此每次第一次执行rand得到的随机数都是相同的.1.多次运行,生成相同的随机数方法:用rand(state,S)设定...
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...
mean(X,DIM) takes the mean along the dimension DIM of X.例1：If dim = dimension = 1, it finds the mean value of each column and returns a row vector containing these means . If dim = dimension = 2, it finds the mean value of each row and returns a column vector containing these...
represent longitude and latitude, the third, depth, and the fourth, time. I also have an integer vector v of size 1x12. How can I obtain a matrix of size (80,50,12), by averaging A along its third dimension, but for eacht, the range use...
mean(x_,outtype) mean(x,missingflag) Here,mean(x)returns the average value for all x components along the first array dimension with a size greater than 1. The average of all the x elements is returned when x is a vector. When x is a matrix, mean(x) gives a row vector that cont...

'mean' : X is padded with the mean along dimension DIM X should not contains NaNs, yielding an all NaN result. NaNs can be replaced by using, e.g., "inpaint_nans" created by John D'Errico. This is an incredibly fast implementation of a running mean, since execution time does not...
