MATLAB: Plotting multiple matlab figures into a single subplot

Question

I used this script to plot 4 matlab figures located in my desktop into a single plot:

Names of the figures: Idc_C1,Idc_C2,Idc_C3 and Idc_C4

clear all;

clc;

c=zeros(4,1);

h=zeros(4,1);

for i=1:4

h(i)=subplot(2,2,i);

end

for k=1:4

% Load saved figures

c(k)=hgload(strcat('C:\Users\kannan\Desktop\PSCAD_Automation_Modell_4T_HBFB\04_Plots\CASE_C1_SEQ_S1\Idc_C',num2str(k)));

% Prepare subplots

figure

% Paste figures on the subplots

copyobj(allchild(get(c(k),'CurrentAxes')),h(k));

end

The problem with the code is that it creates certain duplicated empty figures after the creation of the original subplot.

How should I modify the code to avoid the generation of the empty matlab figures.

Any sugestions or assistance would be very helpful.

Answer 1

Remove figure statement within the loop.

clear all;
clc;
c=zeros(4,1);
h=zeros(4,1);
for i=1:4
h(i)=subplot(2,2,i);
end
for k=1:4
c(k)=hgload(strcat('C:\Users\kannan\Desktop\PSCAD_Automation_Modell_4T_HBFB\04_Plots\CASE_C1_SEQ_S1\Idc_C',num2str(k)));
copyobj(allchild(get(c(k),'CurrentAxes')),h(k));
end
