what is the result?

Pull 20 numbers randomly in the interval [0; 1]. What is the minimum value of the vector and the position of the Coefficient which realizes?

[KL]

It looks like a homework question. Did you try anything yet?

[diadalina]

yes, i know that rand can do this , but when we have 20 element, can anayone help me ?

i'm trying this, but it doesn't be the good result ?

r1=0:1/19:1,
x=rand(length(r1),1)
min(x), and 
[~,i]=find(min(x))

[per isakson]

Read the documentation on min once more

[ m, ix ] = min( x );

[diadalina]

yes, you're right, i can obtain the minimum value of the vector and the position of the Coefficient which realizes with the command min,but the first part of the question, how can i do it, can you help me please ?

Did you read the documentation of rand?

https://de.mathworks.com/help/matlab/ref/rand.html

It says X = rand returns a single uniformly distributed random number in the interval (0,1)

So to generate 20 random numbers, you would use,

 X = rand(20,1);

Then you can use min to find the value and index of the minimum value.
