if true
max=[6 7.75 8.75 9.25 9.50];
min=[5 6    7.75 8.75 9.25];
b=size(max,2);
n=20;
for i=1:b
  c(i)=max(i)-min(i);
  x=sort((min(i))+rand(n,1)*(c(i)), 'ascend')
  y=(linspace(min(i),max(i),n))'
end
end

i want to create 20 random numbers for each c(i), but all the 20 numbers generated for each c(i) should maintain at least .025 gap among themselves. how do i do this? i cant do this with rand or linspace. anyone to help? :(

Thank you sir, but still the numbers are not spaced at least .025 with each other while i examined them in ascending order. these are the output: x =

0175    6.0200    7.8125    8.8275    9.2525
1150    6.1050    7.8200    8.8500    9.2625
2450    6.1475    7.9400    8.9225    9.2675
3250    6.1650    8.0075    8.9625    9.2775
3250    6.2350    8.0800    8.9650    9.3075
3425    6.2550    8.1450    8.9775    9.3400
3750    6.2850    8.1800    9.0025    9.3475
3950    6.5275    8.1850    9.0075    9.3475
3975    6.5675    8.2425    9.0150    9.3575
4375    6.7000    8.2650    9.0275    9.3625
4375    6.9025    8.3025    9.0300    9.3650
4575    6.9450    8.3425    9.0575    9.3975
5475    7.0000    8.3650    9.0600    9.4250
5625    7.1050    8.5700    9.0975    9.4275
5750    7.1500    8.5775    9.0975    9.4350
6750    7.2650    8.6375    9.1100    9.4450
7150    7.4575    8.6375    9.1175    9.4475
7225    7.5050    8.6500    9.1600    9.4600
8150    7.6650    8.6825    9.1700    9.4675
8850    7.7050    8.7475    9.2350    9.4875

see, 5.3250 twice there; 5.3750, 5.3950 & 5.3975 are not .025 distance apart. but i want all of them .025 apart, there should be no chance of repeating same number also. how do i do this, sir?

Please formulate your problem and ask a separate question. Keep in mind that this forum is for questions and answers, not for substitution of work.
