MATLAB: Extracting subplots from a matrix

matrixneurosciencesubplot

Hi!

The data I have is a matrix 16×80, each row is one of the 16th "conditions" (combination of contrasts). Columns correspond to neural activity/traces associated with each condition. I am trying to get 16 subplots from this matrix like below. How can I instruct Matlab to treat each row of this matrix as data for one subplot? Do I have to manually select each row and plot it separately or is there a quicker way, for example using the for loop?

Sorry if it's very basic, I'm a beginner, so would greatly appreciate any help!

use a loop:

% randomized data to illustrate:
M = randn(16,80);
for k = 1:size(M,1)
    subplot(4,4,k)
    plot(M(k,:))
end

I would use histc (or histcounts) and plot the results with bar3:

M = randi(3, 15, 6);                                % Create Data
binrng = 0:4;                                       % Set Bin Ranges
counts = histc(M, binrng);                          % Histogram Counts
figure(1)
bar3(binrng, counts)                                % Plot
xlabel('Columns')
ylabel('Rows')
zlabel('Frequency')

MATLAB: Multiples traces overlapping on multiple subplots

clear
clc
K = rand(16,800,40);
for i = 1:16
	subplot(16,1,i) % subplot(4,4,i)
	for j = 1:40
		plot(K(i,:,j),'b-','linewidth',0.2);
		ylim([-1 2.5])
		hold on
	end
end
