将向量保存到矩阵Matlab中

Question

I have a bunch of arrays that I have generated from a loop

Peaks [1, 2, 3, 4, 5]
Latency [23,24,25,26,27] etc.

I want to put all of those in a matrix that will look like that:

Peaks Latency
1      23
2      24
3      25
4      26
5      27

Then I'll want to save this as a text file.

It seems like it would be fairly simple but can't seem to find anything that closely speaks to me right now.

Answer 1

Concatentate:

>> Peaks = [1 2 3 4 5];
>> Latency = [23 24 25 26 27];
>> T = [Peaks(:) Latency(:)]
T =
     1    23
     2    24
     3    25
     4    26
     5    27

Write:

fileName = 'PeaksLatency.txt';
hdr = {'Peaks','Latency'}
txt = sprintf('%s\t',hdr{:}); txt(end) = [];
dlmwrite(fileName,txt,'');                         % write header
dlmwrite(fileName,T,'-append','delimiter','\t');   % append data

Answer 2

Here is the code

Peaks = [1, 2, 3, 4, 5].';
Latency = [23,24,25,26,27].';

T = table(Peaks, Latency);

writetable(T,'table.txt', 'Delimiter', '\t');

Note that you need to make Peaks and Latency into column vectors (use .' operator).
