help with matlab char arrays
(OP)
Hi
I'm new to matlab, and i'm having some trouble and hope that you can help.
I need to create a 100 row * 500 col array in which each element holds one of 4 letters (a,t,g,c - dna). I'n not sure how to do this, yet.
Will i need to create a for loop? and how can i fill an array in matlab with letters?
I'd really apprciate any help
Thanks for your time

RE: help with matlab char arrays
Here is one solution to your problem
CODE
r = ceil(4*rand(100,500)); % generates random numbers 1-4 in a 100x500 matrix
m = dna(r); % matrix of random dna.

Wow thanks, that works a treat! :D
I've been wracking my brain and had no joy! Had a different approach but your is way better.
I'm gonna have to manipulate this array now and think i have an idea.
Hope you dont mind me pestering you if icant get it to work.
Thanks again!
