How can I create a database from mat-file which contains a 1x1 struct format?

Matlab seems not to recognize the .mat format or don't detect correctly. I specially want to create a TabularTextDatastore

Please attach the sample file you want to read and a more descriptive description of your problem would be helpful.

I'd like to use datastore with tabular text option, because I saw it in a talk. The only difference is they used a .csv file instead a .mat. Can I achieve the same with a .mat file?

Hi,

Kindly have a look at the following link to know about supported files in different Datastore.

• https://www.mathworks.com/help/matlab/import_export/select-datastore-for-file-format-or-application.html

For .mat files, fileDatastore is recommended as shown in the following example

• openExample('matlab/ReadDatastoreOfMATFilesExample').

Thanks.

Thank you very much!! Another doubt, do you know when is useful use database instead a simple table format? Because I have 150 Mb of data and I don't know what is more useful in this case

[Prabhan Purwar]

Datastore is used for large data which you don't want to load at once either due to load time or memory constraints.

[Mario Gutiérrez Morales]

I know, and because of that, do you think that 150 Mb is enough to be considered large data or not? Thanks.

[Prabhan Purwar]

No, but it's really subjective to your hardware capability.

[Mario Gutiérrez Morales]

Thanks again.

It's good practice to accept answers if it's helpful, so that it can act as a reference for others.
