I was trying to create a matrix with text in some cases, but I can't. I tried with advices from other answers, but it didn't work.

The text which I want to include is «start» and «end» for two different cases like this:

NM = 5
FF = zeros(NM*2,2);
start = 'start';
ending = 'end';
i=1
while i<=NM
    FF(i*2,1) = i
    FF(i*2-1,1) = i
    FF(i*2,2) = fprintf(start);
    FF(i*2-1,2) = fprintf(ending)
    i = i+1
end

"it could be possible to get the the solution working with tables?"

Possibly, but as you have not shown what the expected output should be nor explained what further processing you will do using this data, it is hard to give any advice on this.

I need to use this block of data to concatenate with other matrix, after that.

You have to use cell arrays if you want to mix text and numbers. And fprintf returns the number of printed bytes, so you directly assign the string to the cell, w/o fprintf:

NM = 5
FF = cell(NM*2,2);
start = 'start';
ending = 'end';
i=1;
while i<=NM
    FF{i*2,1} = i;
    FF{i*2-1,1} = i;
    FF{i*2,2} = start;
    FF{i*2-1,2} = ending;
    i = i+1;
end
