How to get 10000 variable numbers between the range of 0 and 100?

i want a variable array of 10000 numbers from 0 to 100.

a = -5; b = 5; varx = a + (b-a).*rand(10000,1); varX = 10.^varx;

so i want this in the above format.

can you help me out?

[Md. Atiqur Rahman]

a=randi([0,100],[1,10000])

or,

a = -5 + (5+5)*rand(1,10000)

[Star Strider]

Note that because of:

varX = 10.^varx;

and the set limits, ‘varx’ will be between and . Is that what you want?

[Aniket Dutta]

actually i want the values between 10^(-5) and 10^2.

If you want the numers to be between and , use the logspace function, then use randperm to randomise them —

varx = logspace(-5, 5, 1E+5)                    % Generate Vector

varx = 1×100000

1.0e+05 * 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000

varx = varx(randperm(numel(varx)))              % Randomize It

varx = 1×100000

1.0e+05 * 0.0000 0.0000 0.0000 0.0000 0.0000 0.0001 0.0000 0.0000 0.0000 0.0241 0.0000 0.0002 0.0000 0.9879 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0282 0.0000 0.0000 0.0000 0.0014 0.1385 0.0000 0.0000 0.0000

Check = [min(varx) max(varx)]                   % Check Result

Check = 1×2

1.0e+05 * 0.0000 1.0000

log10Check = log10(Check)                       % Verify 

log10Check = 1×2

‘actually i want the values between 10^(-5) and 10^2.’

varx = logspace(-5, 2, 1E+5)                    % Generate Vector

[Abderrahim. B]

Try this --

varx = 100*rand(10000, 1) ;
min(varx)

ans = 0.0227

max(varx)

ans = 99.9844
