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.

im now trying uigetfile/uigetdir in this case.. still confuse with this command. i also used evalin to display the figure and there are errors

[Walter Roberson]

Example:

[filename, pathname] = uigetfile('Choose the input file');

completepath = fullfile(pathname, filename);

data = load(completepath);

fn = fieldnames(data);

current_data = data.(fn{1});

is there any way i can display the figure without opening the box the contains my file? i want it to display right away after i click the pushbutton

[Walter Roberson]

If you already know the path to the file, then

data = load(completepath);

fn = fieldnames(data);

current_data = data.(fn{1});

[bing zeth]

data = load(completepath);

>>actually,how to write the completepath? I dont want to use the uigetfile command,i want the figure displays right away
