MATLAB: Random complete and in complete numbers

range of random 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

MATLAB: Non-repeating random integer generator with a seed

According to the doc for randperm, it uses the same random number generator as rand, randi, and randn. So you can control the seeding with rng (even though randperm isn't mentioned in the rng doc). E.g.,

>> rng('default')
>> randperm(10)
ans =
     6     3     7     8     5     1     2     4     9    10
>> randperm(10)
ans =
     6     1     7     4     9     5     8     3    10     2
>> randperm(10)
ans =
     2    10     8     9     1     5     7     6     3     4
>> rng('default')
>> randperm(10)
ans =
     6     3     7     8     5     1     2     4     9    10
>> randperm(10)
ans =
     6     1     7     4     9     5     8     3    10     2
>> randperm(10)
ans =
     2    10     8     9     1     5     7     6     3     4

MATLAB: Streamline plot not complete

Works ok for me

N = 15; 
xx = linspace(min(x(:)),max(x(:)),10);
yy = linspace(min(y(:)),max(y(:)),10);
[startx,starty] = meshgrid(xx,yy);
streamline(x,y,u,v,startx,starty)
