Making a movie from the data files in matlab

[vissu219]

hi guys..i have a set of datafiles(more than 500)for each set i have to plot a graph and make a movie with them.. i want to knw how do i load all these files and plot them in a loop..the files are named as v1 v2 etc...and simeltaneously generate frames and make a movie.pls help ppl..

simple example from a m - file have on "desk". The way usually do it is to inquire what files exist in a folder (using internal MATLAB commands for this) or derive the filenames using text-processing functions like strcat below, and then do the reading and storing in a for loop. Further processing then similarly, easiest to do it all in m - files.

%creating a cell array for data storage
all_data=cell(number_of_files,1);

for i=0:number_of_files-1
    %filename for current read
    filename_reading=strcat(input_path,specimen_id,'_',int2str(i) ,'.matlab_ascii');
    %reading all data to a cell array, +1 to get proper indices    
    all_data{i+1}=dlmread(filename_reading);
end

number_of_files, input_path, specimen_id are strings defined previously.

I would suggest using a programming language, such as Python, to automate the process of loading and plotting the data files in a loop. This will save time and ensure consistency in the plots. Additionally, there are libraries specifically designed for creating movies from data, such as Matplotlib's animation module. These libraries allow for easy customization of frames and can handle large amounts of data. I would also recommend organizing the data files in a logical manner, such as by date or experiment number, to make it easier to load and plot them in a loop. Overall, using a programming language and specialized libraries will make the process of creating a movie from the data files in MATLAB much more efficient and accurate.
