I have some data in a directory saved in various folders with name 1_1_1, 1_1_2, .... etc. All files in those folder have same name. I have defined a for loop and in that I want to cd to required folders (1_1_1, 1_1_2,....) one by one. Hence in the pathname I need to input the loop varibales. Please see below script.
clear;clc
for a=1:1:1
for v=1:1:1
for s=1:1:10
formatSpec='/media/satyajit/My_Passport/Satyajit/Extra_Backups/folder1/folder2/%d_%d_%d';
str=sprintf(formatSpec,a,v,s);
cd str
Script_1
Script_2
end
end
end
But, it is showing error - "Error using cd
Cannot CD to /home/satyajit/str (Name is nonexistent or not a directory).
Error in Master (line 27)
cd str"

Do not change directory just to import/export data files.
Use absolute/relative filepaths instead, it is more efficient and easier to debug.

P = '/media/satyajit/My_Passport/Satyajit/Extra_Backups/folder1/folder2';
for a=1:1:1
for v=1:1:1
for s=1:1:10
T = sprintf('%d_%d_%d',a,v,s);
F = fullfile(P,T)
... use the filepath F here
end
end
end
Note that you can even call scripts in any folder using RUN.
