Work with data just in selected paths

Hello together,

I have special folder with data (ex.):

FilePath1 = '/home/user/workspace/QT/Software_2.0_QT/IO/Motor_Set_1/AKG_C1000S/Distance_0.5m/Scenario_M1/001_m1_60_const_20200611_200515'

FilePath2 = '/home/user/workspace/QT/Software_2.0_QT/IO/Motor_Set_1/AKG_C1000S/Distance_0.5m/Scenario_M1/002_m2_60_const_20200811_200411'

inside are different .mat files.

I want calculate data with just this two paths.

addpath(Filepath1);

and

addpath(Filepath2);

are not working. And if my current MATLAB folder

'/home/user/workspace/QT/Software_2.0_QT/IO/Motor_Set_1/AKG_C1000S/Distance_0.5m/Scenario_M1'

MATLAB starting to work with all foler inside:

001, 002,003,...030.

And i want just 001 and 002

How can I choose and lock my working folder?

Thank you!

Hi!

Could you check in the lists of all search paths if you have accidently added those subfolders? You can check it using the 'Set path' dialogue box. Find it in the Home tab, in the Environment section.

Using the same dialogue box you can add or remove the folders you want.

Hello, yes, thank you, i tried it allready.

The problem is - for example, I have in one Folder, three subfolder - 001, 002, 003

I do, addpath(001) and addpath(003) (without adding 002) and than want find and analyse all mat.file from folder in subfolder 001 and subfolder 003. And MATLAB still find 002 and show me an error:

Error using load
'002.mat' is not found in the
current folder or on the MATLAB path, but exists in:
    /home/user/workspace/QT/Software_2.0_QT/IO/Motor_Set_1/AKG_C1000S/Distance_0.5m/Scenario_M1/002_m1_30_90_triangles_20200611_200554/SNR_F1
    
Change the MATLAB current folder or add its folder to the MATLAB path.

Error in analysis_algorithms_23_06_20 (line 41)
load(file_name)

How can I avoid this?

[Aditya Verma]

What is the exact command you are using to load the files?

[Nik Rocky]

load(file_name)

file_name =

    '001_m1_60_const_20200611_200515_SNR_019_PLL.mat'

[Aditya Verma]

Okay, so the way it works is that it checks all the paths for the file specified in load command. If the file is not found, then only it gives an error, which is expected behaviour. Here, in this case it also gives a suggestion along with that error.

[Aditya Verma]

I still don't understand what you want to acheive. Do you want to suppress the error?

[Nik Rocky]

I want to compare mat.file from subfolder 001 with mat.file from subfolder 003.

All subfolders are in one same folder.

I would prefer to write in a code:

load data x from folder 001

load data y from folder 003

compare x and y
