Try this:

x = 23;
str = sprintf('%3.3d', x)
fprintf("hundreds  :%s\n", str(1));
fprintf("     tens :%s\n", str(2));
fprintf("    units :%s\n", str(3));
x = 456
str = sprintf('%3.3d', x)
fprintf("hundreds  :%s\n", str(1));
fprintf("     tens :%s\n", str(2));
fprintf("    units :%s\n", str(3));

oh yah ! tks you very much

You said what you really wanted instead of percents in your comment to Star:

"i mean i want to calculate the tens digit of any number from (100 > 999)"

My code produces:

str =

'023'

hundreds :0

tens :2

units :3

x =

456

str =

'456'

hundreds :4

tens :5

units :6

Isn't that exactly what you asked for?
