Are you trying to display a numeric result (in which case you should use the format function to change the format used to display numeric results) or a symbolic result (in which case you could use vpa)?

Digits() only affects floating point symbolic numbers; it has no affect on double precision or single precision.
There is no method to get exactly 6 digits in the command window. "format short" will give you 5 digits, and "format long g" will give you 15 digits. There is no way to customize the display to 6 digits.
However... if you were to round(TheData, 6) and display it with "format long g" in effect, you would mostly see 6 or fewer digits
format short
A = rand(2,5);
A
A = 2×5
