I have a large array, where i should search for 101 and replace it by 102102,,, 105 by 106106,,,,,109 by 110110,,,113 by 114114...and check upto 289 and replace by 290290... it is nothing but adding 4 and check for that number and replace it by next occuring number twice... Can anyone help me in generalizing this....
Thank you...

Example
a=randi(1000,1000,1)
b=a(a>=101 & a<=289)
c=num2str(b+1)
d=str2num([c c])

Performing operations on numbers is usually faster without changing the type of the data:
a = randi(1000,1000,1);
idx = (a>=101 & a<=289);
a(idx) = (a(idx) + 1) * 1001;
