I try to do better:

Oh, I didn't mean to criticise, just to explain that any problem needs to be defined before it can be solved.

a) Both matrix have column A (The first Matrix is in Sheet 1 and the second Matrix is in Sheet 2) b) I want to compare the content of A1 of the first Matrix with all the column A of the Matrix 2 searching an equal or similar content string there. The content in all rows of the column A of the Matrix first is different between them. In second Matrix too. c) I need continue to do this with A2...An of the first Matrix with all the column A of the Matrix 2

Actually, most of that was clear previously. Since you are now comparing cells from different sheets, instead of
you need something like
- filled down a column, of course.

But as soon as you use a word such as "similar", that needs defining accurately before you can construct the formulae you need. LibreOffice will not read your mind. Are "My dog's name is Fido" and "My dog's name is Rover" similar? Are "My dog's name is Rover" and "I often buy rover tickets" similar? Are "My dog's name is Rover" and "Today is Monday" similar? (They both contain "is".) Are "16th November" and "November 16th" similar? Are "The cat sat on the mat" and "The cat sat on the mat." similar? How about "Jorge Rodríguez" and "Jorge Rodriguez"? Or "John Smith" and "John Smith"?

You also haven't clarified what sort of result you need: is a simple column indicating whether each row satisfies your similarity criterion (as produced above) what you need?

I trust this helps.
