How to display a group of subplots as a movie? - matlab

Question

I have 30 heatmap subplots. How could I present these subplots as an animation or a movie (i.e. one heatmap each 0.5 seconds)?
The subplots are obtained with the following code:
var = {'GeneX','GeneY','GeneZ'};
syms x y z S
alpha_x = 3.9e-2;
beta_x = 6.1;
z_x = 1.3e-5;
n_zx = 2.32;
alpha_y= 4.3e-2;
beta_y = 5.7;
x_y = 7.9e-4;
n_xy = n_zx;
delta_y = 1.05;
x_z = 12e-2;
n_xz = n_zx;
y_z = 11e-3;
n_yz = n_zx;
delta_z = 0.2;
ACDC_X = (alpha_x+beta_x*S)/(1+S+(z/z_x)^n_zx)-x;
ACDC_Y = (alpha_y+beta_y*S)/(1+S+(x/x_y)^n_xy)-delta_y*y;
ACDC_Z = 1/(1+(x/x_z)^n_xz+(y/y_z)^n_yz)-delta_z*z;
ACDCsys_div = [ ACDC_X, ACDC_Y, ACDC_Z ];
J = jacobian(ACDCsys_div,[x;y;z]);
Jsolnew(x,y,z,S) = [J];
%%Construction of the coordinates as a matrix
A = load('matlab.mat','unnamed');% import data from directory
a2 = struct2array(A);% coordinates of the equilibrium point.
numofGraphs = 80;
bx = length(a2(1,1:numofGraphs));
%% Construction of the heatmaps
figure;
hmapax = ceil(sqrt(bx));
for kk = 1:bx %bnx %All bin windows = iteration
JacACDCnew(:,:,kk) = Jsolnew(a2(1,kk),a2(2,kk),a2(3,kk),a2(4,kk));
ACDC_HmapJnew = double(JacACDCnew(:,:,kk));
subplot(hmapax,hmapax,kk);%
heatmap(var,var,ACDC_HmapJnew,'ColorScaling','log');
S = a2(4,kk);
title(['Jac','s=',num2str(S)]);
end

Answer 1

Consider the following example:
function q56130816
% Load some data:
frames = imread('https://i.stack.imgur.com/03kN8.gif');
frames(frames > 1) = 2;
% Create subplots:
figure('WindowState','maximized'); subplot(2,4,1);
for ind1 = 1:8
subplot(2,4,ind1);
imagesc(frames(:,:,1,ind1)); axis image; axis off;
end
colormap([255 255 255; 188 188 188; 244 128 36]./255);
% Capture subplots as frames:
for ind1 = 8:-1:1
frameHolder(ind1) = getframe( subplot(2, 4 ,ind1) );
end
% Play as movie:
hF = figure(); movie(hF, frameHolder, 20, 2);
Which will turn:
Into:
As you can see, in the example above I used getframe, but frames can also be captured using print, as mentioned in the getframe docs. Frames can also be exported to a video file, as explained here.
Animation credit: frames were screen-captured from Johan Lindell's Codepen example.
