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?

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
-5 5

‘actually i want the values between 10^(-5) and 10^2.’
varx = logspace(-5, 2, 1E+5) % Generate Vector
varx = 1×100000
1.0e+00 * 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
12.2648 28.3893 0.0239 0.0008 4.9518 2.1702 0.0146 0.8131 0.2272 0.0000 0.2467 0.4178 5.3700 9.1466 28.9484 53.1701 0.0206 0.0001 0.0094 0.0249 2.5477 41.2094 1.6019 0.3318 41.3358 0.0008 66.8018 0.0000 0.7349 18.7881
Check = [min(varx) max(varx)] % Check Result
Check = 1×2
0.0000 100.0000
log10Check = log10(Check) % Verify
log10Check = 1×2

Try this --
varx = 100*rand(10000, 1) ;
min(varx)
ans = 0.0227
max(varx)
ans = 99.9844
