Plot vectors in cell array over for loop
显示 更早的评论
I have the following data structure (a cell array populated with vectors):
sigvecarray = {};
freqarray = {};
% Reading the audio files, getting the signal vector and the corresponding
for k = 1:numel(inputarray) % indices
curr_input = inputarray{k};
[y, Fs] = audioread(curr_input);
sigvecarray{k} = y;
freqarray{k} = Fs;
end
I'm trying to plot them over a for loop by using the following:
for k = 1:numel(sigvecarray)
plot(sigvecarray{k})
end
But I get only the fist vector plotted as my output. What could I be doing wrong here? Is it because the cell array is a row vector? If yes, how do I convert the cell array to a column vector from a row vector?

figure
hold on
for k = 1:numel(sigvecarray)
plot(sigvecarray{k})
end

Yes, you can use subplot if you want it on different plots. You can use subplot in a loop depending on how many plots are there.
k = 5;
for i = 1:k
subplot(k,1,i)
plot(rand(1,10))
end

Possible you need to set the size of whole figure etc....read the doc.

hold on
will add new lines on the same axes without deleting old lines.

You need to use the Position property of the axes object to change their size. An alternative might be to use
nexttile(): https://www.mathworks.com/help/matlab/ref/nexttile.html. Though I am not sure if there is a significant difference.
