How to define a path in saveas command?
显示 更早的评论
Hey Matlab users,
I've got a problem in defining a path for saveas command. When i want to save my Figure, the file is directly been saved in a path that is already on top of the command window in front of the "Current Folder". I tried to change the address by fname:
fname = 'D:\path1\path2';
saveas(gca,filename,'jpeg');
But it didn't work!!!
I very much appreciate your hint :) Mehdi

You have to consider the variable fname in the call of saveas:
fname = 'D:\path1\path2';
saveas(gca, fullfile(fname, filename), 'jpeg');
I assume "fpath" would be more meaningful than "fname".

Inorder to save file on to the same directory where my matlab program is there, I used to use this command:
print('-dpng',['FirstVar',num2str(A),'SecondVariable',num2str(B),'ForLoopIndex',num2str(i),'.png'])
How can I modify your code to accomplish this?

To accomplish what? Where is your "matlab program"? Do you mean matlab.exe or an M-file? Is it a compiled application?
I find this version easier to read:
FiileName = sprintf('FirstVar%dSecondVariable%dForLoopIndex%d.png', A, B, i);
File = fullfile(Folder, FileName)
print('-dpng', File);
I guess, that you want to file to be stored in the folder of the M-file. Then:
Folder = fileparts(mfilename('fullpath'));

@Jan, extremely sorry for posing the problem in a bad way.
I have a matlab code located at “D:\FolderA” which is used to analyze data located at “E:\DataFiles”. Matlab code will generate some plot, which I want to save in “E:\DataFiles”. If I wanted to save the file in the same folder where my program is, the I was using :
print('-dpng',['FirstVar',num2str(A),'SecondVariable',num2str(B),'ForLoopIndex',num2str(i),'.png'])
My question was what if I want to save it to “E:\DataFiles”.
Your solution helped me. Thank you

I need help to save an stft fig file format to .bmp file format. Can someone help me pls..im stuck for multiple weeks. this is my code
clear all; clc
%%read file by selecting the files

Currently the saving is only saving .eea file. what i trying to do in this project is trying to plot the signals from .eea file format transform them to fig file format then i trying to save the fig file format to .bmp. Kindly advise. Thank you

...
for i=1:length(file_list)
filename = file_list{i}; % Now filename contains the .eea extension.
... % Your code
FolderName = 'C:\Users\Acer\Desktop\FYP 2021\Matlab (Proj)\Channels Split (STFT)\Schizophrenia (Combine Channels)';
[~, file] = fileparts(filename); % Remove extension
saveas(gca, fullfile(FolderName, [file, '.bmp']); % Append .bmp
end

You can either change directory to the directory you want to save it in, or you can specify the directory
plot(randn(100,1));
save(gca,'c:\figures\test','jpeg');

Also if you want to define your figures directory
figuresdir = 'D:\figures\';
saveas(gcf,strcat(figuresdir, 'filename'), 'jpeg');

Instead of 'strcat' it is better to use the 'fullfile' function because it will handle the file separator and will work in different operating systems (will place correctly '\' in Windows, '/' in Linux etc.)
saveas(gcf, fullfile(figuresdir, 'filename'), 'jpeg');
