Adding semicolon into data

Question

0 个投票

Hi guys, I'm using Matlab 2014b (I don't have access to a better version) and I have a set of data like this:

A=x1,x2,x3,x4,x5,x6,...,xn

I need to add a semicolon for every pair, so I get sth like this:

A=x1,x2;x3,x4;...;xn-1,xn

How can I do that?

I created A using dlmwrite, but when I try to use delimeter in this function I get the following error:

"Delimeter is not a valid attribute or delimiter. Delimiter must be a single character"

Can anybody help?

I don't have access to writematrix function.

I'm confused.

When you say you have "a set of data" ... what exactly do mean? Is A a MATLAB (numeric) row vector?

Are you trying to write that vector to a file? With some semicolons?

Also, is it possible that part of the problem is that you misspelled the word "delimiter", which is why MATLAB couldn't interpret it?

I had two vectors:

x=(x1,x2,x3,...,xn)

y=(y1,y2,y3,...,yn)

Then,

z=[x(:),y(:)] ';

dlmwrite('z.txt',z)

This what I've done so far and I get this the txt file like this:

z=(x1,y1,x2,y2,y3,...,xn,yn);

Actually, it worked, but the semicolon is added for every single point, not for every pair

dlmwrite('z.txt',z,'delimeter',';')

From another post:

Try this low-level code:

-----------------------------------------

x = randi(9,[1,2*6001]); % ACTUAL DATA

fileID = fopen('data.txt','w');

for k = 1:2:numel(x)-1

fprintf(fileID,'%g,%g;',x(k),x(k+1));

end

fclose(fileID);

-----------------------------------------

Enjoy!
