Hi people, pls help; i wrote a matlab program to find the logarithm of the average of a signal energy for twenty(20) different audio files. for each session of my code, i saved my output as 'E'and matlab display E=.... for all different 20 audio files. but what i want is for matlab to display my answer together as a [20,1] matrix. that is E=.......... for all 20 answers instead of displaying individual answer. does anyone know if it is possible for me to achieve this? secondly, is it possible to automatically convert my output to txt format? i will appreciate any assistants. thanks

Alternatively the data can be written straight away, without saving it in an intermediate matrix:
fid = fopen(filename);
for k = 1:20
... read file
... calculate energy
fprintf(fid,...)
end
flcose(fid)

Iamawal - if you have a program to find the log of the average signal energy for 20 audio files, then you must be using a for loop to do this. If this is the case, then just create a matrix for this output prior to iterating. Then, on each iteration, store the energy in this matrix. Something like
E = zeros(20,1);
for k=1:20
% read the audio file
% calculate the energy
% save to the matrix
E(k,1) = ...;
end

Iamawal - please don't post the same question in two different places. Your question at http://www.mathworks.com/matlabcentral/answers/165348-k-fold-validation-speech-recognition should be sufficient.
