How Can I Automatically Load .mat Files in MATLAB?

[mathia]

Hi,

I have some *.mat files and I need to read them automatically, they are like:
PT2020-RSK1.778-ZONE49.8962.mat
PT2020-RSK2.776-ZONE47.5451.mat
PT2020-RSK3.776-ZONE46.041.mat
PT2020-RSK4.7695-ZONE56.5417.mat
PT2020-RSK5.7667-ZONE48.1113.mat

Are there any ways to load them into MATLAB automatically?

Thanks for your time.

Regards,
Mathias

You can use the load command. If you want them loaded from a script try something like

load [COLOR="DarkOrchid"]PT2020-RSK1.778-ZONE49.8962.mat[/COLOR];

if you want them to always be in your workspace you can put the load command in your startup.m.

Thanks, But I want to load them automatically, I don't want to type the name of each individual mat file because I have 100000 mat files.

Put them in all in one directory then and play with the "what" command. So you'd do something like:

K = what(directory)

And now K will be a structure with the filenames, then you can just go through each K.mat with a for loop

for example:

for i = 1:length(K.mat)

load(K.mat{i})

(do stuff with it)

end

Hi Mathias,

Yes, there are several ways to load *.mat files into MATLAB automatically. One method is to use the "load" function, which allows you to specify the file name as an input. For example, you could use the following code:

data = load('PT2020-RSK1.778-ZONE49.8962.mat');

This will load the contents of the *.mat file into the variable "data". You can then access the data within the file using the appropriate variable names.

Another method is to use the "dir" function to obtain a list of all the *.mat files in a specific directory, and then use a for loop to load each file one by one. This may be more useful if you have a large number of files to load.

I hope this helps. Let me know if you have any further questions.

Best,
