MATLAB中向量的级联 [英] Concatenation of Vectors in MATLAB

问题描述

我在MATLAB中有这10个向量，均值(alltmws {l}')，其中l为1到10.每个向量的大小为1X10001.现在，我想将所有这些值存储在一个向量中，一个接一个地存储，以便我可以计算和绘制总体均值.我该如何进行串联?任何帮助将不胜感激.

I have these 10 vectors in MATLAB, mean(alltmws{l}'), where l is from 1 to 10. The size of each of these vectors is 1X10001. Now I want to store all these values in one vector, one after the other, so that I can calculate and plot the overall mean. How can I do this concatenation? Any help will be greatly appreciated.

推荐答案

例如，如果您有

a{1} = rand(10,1);
a{2} = rand(10,1);
a{3} = rand(10,1);

你可以做

A = [a{:}];
A = A(:)

这个问题是模棱两可的，但是如果这是人们想要串联和绘制的方式，则可以执行以下操作:

The question is ambiguous, but if it is the means that one wants to concatenate and plot, you can do:

% Create example data
data = {};
for k = 1:10
  data{k} = rand(100,1);
end

% Compute and plot array of means
mu = []
for k = 1:length(data)
  mu(k) = mean(data{k});
end
plot(mu)
