Generating random numbers using for loop

Hi, Shall i use the following code to generate random numbers and use them further in the calculation?

clear all
close all
 for n=1:2;
     h(n)=rand
 end

[Praveen]

rand(0,1)

Answer 1

If you like. you could instead pass size information to rand to say how many items to generate .

Sir how?

Answer 2

[KSSV]

N = 10 ;
iwant = zeros(N,1) ;
 for n=1:2;
     iwant(n)=rand ;
 end
 iwant

OR

N = 10 ;
iwant = rand(N,1) ;

@Maheen Fazal did you look at the help? If you would, you'd see info like this:

Random Numbers Within Specified Interval

Generate a 10-by-1 column vector of uniformly distributed numbers in the interval (-5,5).

r = -5 + (5+5)*rand(10,1)

r = 10×1

0.3467 -2.7506 0.3305 -0.3516 0.4854 4.9774 -4.3315 -4.5855 -3.7174 1.3212

So, for you:

h = rand(1, 2)

h = 1×2

0.1069 0.1859
