Add specific numbers to a plot

I have a code that I am calculating some values. I would like to add this values to a spesific point in my plot (I mean I would like to add upper left the folowing: 'A = 5', (to a next row 'B= 10' etc). I think I should use num2str(A) function but I do not know how.

Could you help me?

Read about the function text.

I have tried this but the problem is tha the "results" are not showing in the same row.

I have tried this:

str={{'A=', {num2str(A)}}
text(3,8,str)

but no use.

Could you help me?

text(3, 8, sprintf('A=%g', A))
