Hello,
I want to generate a random number generator 0 to 1 should include values with ten decimal points.As default i get only 4 decimals.
Thanking You,
Sita

Where did all the comments go? Did you delete them? If so, why? Without them our answers looks a little bit unmotivated, not to say lunatic. Therefore removing important data from a thread is not wanted.

out = rand(1, 1);
decimal_out = floor(out * 100000000);
decimal_out = decimal_out\100000000;

Don't you mean "decimal_out/100000000"?

Your're right, that's a typo, must read /. Of course you can do it more efficiently in one line (for example, to generate a row vector of four random values):
x = floor(rand(1,4)*1e10)/1e10;

What about using rand() directly, because it satisfies: at least 8 decimal digits already?

The limitation to 4 digits appears in the command line only, see: help format.
format long g
disp(rand(2,2))
Although I assume your code is just an abbreviated example, I recommend not to use "min" and "max" as names of variables, because this shadows frequently used Matlab commands.
However, I still do not understand your question. What does "fixing the number of decimal points" mean? RAND does reply values like 0.00000000001 also, so what is the problem.

Do you have the distribution law for pseudo-random numbers for your problem? You can use RAND function for generate uniformly distributed numbers and define its non-linear (or linear) transformation function:
numbers = rand(10);
transformedNumbers = transform_function(numbers);
