在矩阵内混洗数据 [英] Shuffling data inside a matrix

问题描述

我有一个名为drt的矩阵，它是1x200，只包含整数值，我想在矩阵内混洗这些值。请问我该怎么做，我尝试了randperm和randsample，但是他们没有工作。



欢迎使用C或Matlab的答案。谢谢



我尝试了什么：



％创建一个数组，并用1到1的数字填充它fsum

fsum = 200;

randm = zeros（1，fsum）;

for rn = 1：+ 1：fsum

randm（1，rn）= rn;

结束

％来洗牌阵列

randm = randm（randperm（长度（randm）））;



或



randm = randsample（randm，fsum）;

I have a matrix called drt which is 1x200 which contains only integer values and I want to shuffle these values inside the matrix. please how do I go about it ,I tried randperm and randsample but they are not working.

Answers in C or Matlab is welcomed.Thanks

What I have tried:

%create an array and fill it with numbers from 1 to fsum
fsum=200;
randm=zeros(1,fsum);
for rn=1:+1:fsum
randm(1,rn)=rn;
end
% to shuffle the array
randm=randm(randperm(length(randm)));

OR

randm=randsample(randm,fsum);
