add index to matrix's rows

I have a matrix like below:

A= [1 2 4

3 4 2

2 4 5]

With n rows and three columns. I would like to create the following

1: 1 2 4

1: 3 4 2

1: 2 4 5

Thank you all in advance.

Can you be more specific about what you mean by "I would like to create the following"? For example, do you want to

• display those strings to the command window?
• create or display a cell array with text and numeric entries?

Please give us more detail.

I would like to print the data like below:

I think it would be better if I do it with fprintf

what is your suggestion?

1: 1 2 4

1: 3 4 2

1: 2 4 5

Here's one way:

fprintf('1: %d %d %d\n',A')

For more complicated examples, you might want to read about the formatSpec in the documentation for fprintf.
