I wanna create a txt file and assign data from matlab variables into this file. The point is I wanna create txt file without opening any file like in the case of "save as" in world or excel. I also want that user can choose directory and file name.

1 visualizzazione (ultimi 30 giorni)
for example,
p = rand(5, 3)
startingFolder = 'C:\Program Files\MATLAB'
if ~exist(startingFolder, 'dir')
startingFolder = pwd
end
defaultFileName = fullfile(startingFolder, '*.txt*')
[baseFileName, folder] = uigetfile(defaultFileName, 'Select a file')
if baseFileName == 0
return
end
fullFileName = fullfile(folder, baseFileName)
save(fullFileName, 'p', 'q', '-ASCII')
in here, I want that users don't have to need to open any file before saving data into this file , like in the "save as". So users would choose path and file name in the same dialog box once, then file would be saved directly without creating a blank txt file before.

I'm not sure you can using "save".
I'm not sure what you're really aiming for, but "dlmwrite", "csvwrite", and "xlswrite" are probably better suited to outputting nicely formatted text.
