here is the code for open existing ppt and get the no of slides.

Now next task is that how can I replace figures by new figures from existing slides

Thank you in advance!!

clear all; clc;
project_dir = pwd();        %new
% List all current folder contents ending with .png. Resulting names will
% appear in the order returned by the operating system.
files = dir( fullfile(project_dir, '*.png'));    %changed
% Create Common Object Model (COM) server so MATLAB can export data to
% PowerPoint
g = actxserver('powerpoint.application');
% Open PowerPoint and make it visible
g.Visible = 1;
Presentation = g.Presentation;
% Prompt the user for the PowerPoint file to amend
[fn, pn] = uigetfile('*.pptx', 'Select PowerPoint File To Amend');
filename = fullfile(pn, fn);                                %changed
Presentation = invoke(Presentation, 'open', filename);
% Get current number of slides
slide_count = get(Presentation.Slides, 'Count');

clc
clear all;
close all;
import mlreportgen.ppt.*
slidesFile = 'myPicturePresentation.pptx';
slides = Presentation(slidesFile);
add(slides,'Title Slide');
add(slides,'Title and Content');
plane = Picture(which('b747.jpg'));
plane.Width = '5in';
plane.Height = '2in';
replace(slides,'Content',plane);
close(slides);

This requires the MATLAB Report Generator, I believe.

It would help if the code could show selecting a particular slide given the index.

I have tried this earlier but it does not completely apply to my application.

earlier code adds image in new slide but I want to add in only in existing slide

Is there any way by which I can add image to specific existing slide in specified location?

actually my task is to only update .png file into std format of ppt which is repetative work

my ppt format is of following type:
