Random complete and in complete numbers

I have tried using Randi function,but it only gives me complete numbers.also tried rand but it doesn't give me to choose a specific range. Is there a function in matlab that would give me both complete and incomplete numbers in a specific range?I need to put this numbers in a matrix

To randomize uniformly over an interval [lower, upper], you would do,

out=rand(___)*(upper-lower)+lower

Where I can put the range of numbers ?because when I tried to put it gives me an error

Are you sure you looked in the help, because it does give you examples for how to specify a range.

[Matt J]

For example, to generate a 5x4 matrix of numbers uniformly distributed between 7 and 9,

A=rand(5,4)*(9-7)+7;

I find that there option for me to choose a range in Randi function(that only gives complete numbers),but not in rand

[Stephanie khoury]

Thank you so much?

[Matt J]

that only gives complete numbers

No, you can use randi to generate any range of integers, not just the whole numbers. For example,

>> A=randi([-9,-7],5,4)

A =

    -7    -7    -8    -7
    -8    -7    -7    -7
    -7    -9    -9    -8
    -8    -7    -7    -9
    -9    -8    -8    -7

See the "Random Numbers Within Specified Interval" example on the documentation page for the rand function.
