You don't have to create a file. carsmall is a mat file. Loading it loads all the variables you need into your workspace.

I just saw your question about reading your Excel file back in. What is it you are trying to do with this example?

[Cris LaPierre]

If you have not yet done so, I strongly recommend you go through MATLAB Onramp. It's a ~2 hour intro to the basics of using MATLAB.

Thanks for your reply.

What I need is I want to create a file similar to the "carsmall" file which is using my own dataset.

[Cris LaPierre]

Create your data in MATLAB, then use the save command to create a mat file of your own containing your data.

Thanks.

May I know how I can create a data in MATLAB?

In the past, I created my data in csv file and then call csv file in my MATLAB.

[Cris LaPierre]

Depends on what your data is. If you need help with this, my recommendation would be to go through at least a couple of the initial chapters in MATLAB Onramp to learn about creating variables and importing data.

Creating it in a csv file and loading it also works. It's just you mentioned wanting to create a file like carsmall, which means you have to first create the variables in MATLAB then save.

Thanks.

I only want to create a file in carsmall as shown in the figure below:

I do not understand the meaning of the screenshot and do not know, what "in carsmall" means. You can create a char array by:

a = 'hello'

[Matlaber]

Thanks.

It works

a = 'hello'

Let say I want to do a multiple char

like this below:

Test1

Test2

Test3

Test4

Test5
