end ___________________________________________________________________ This is the edited m file for simple_gui2. I want to change the figure to the figure frommy file which have the directory path as this one,C:\Users\SONY\Documents\MATLAB\a. How can i put this figure into my figure simple_gui2. I want this figure from the file appears as I click the pushbutton. How should i program it?
Thanks

Replace the line
current_data = peaks_data;
with a line that loads the data from your file and stores the image data array in the variable "current_data". If you want the user to be able to select the file to load, use a call to uigetfile().
Caution: the routines will only work properly for black-and-white or grayscale images. Indexed (pseudocolor) images will not crash the program but will give you different results than you expect. RGB (truecolor) images would crash the program as the processing routines used here are not expecting 3-dimensional arrays.

Example:
[filename, pathname] = uigetfile('Choose the input file');
completepath = fullfile(pathname, filename);
data = load(completepath);
fn = fieldnames(data);
current_data = data.(fn{1});

If you already know the path to the file, then
data = load(completepath);
fn = fieldnames(data);
current_data = data.(fn{1});
