Hi,

This is my first thread in this forum. Hope somebody will help me.

I am writing a simple Matlab program and in that I have an array of numbers with repeating numbers. I want to extract the dissimilar numbers and put in an array. I used below method to do that and it seems to work.


a=1;

for k=1:(2^n-1)

if Logpp(k)~= Logpp(k+1)
Logpp_val(a,1)=Logpp(k,1);
a=a+1;
k=k+1;

else
k=k+1;

end

end

Here I compare the numbers in the original array if they are not equal I write that to the final array.

I'd like to know whether there's an easier or rather optimized way to do this Matlab as I need to repeat this often in the program.

Thanks in advance for the help.

You can use function "unique".

B = unique(A) for the array A returns the same
values as in A but with no repetitions. B will
also be sorted.

Type
help unique
on your command window to see the full description.
