In MATLAB,I have a 1 x 8 cell array.The numbers are
-4.5,-1.5 ,-2.5,-1.2,1.2,2.5,1.5,4.5
I iterate through the whole cell.I take absolute values of each element.As soon as i encounter equal elements (Here it is going to be 1.2 and 1.2), i add a zero in between them. Overall it becomes a 1 x 9 cell array.Kindly help me with this.

>> V = [-4.5,-1.5 ,-2.5,-1.2,1.2,2.5,1.5,4.5];
>> Z = V;
>> Z(2,:) = 0;
>> Z = Z([true(size(V));~diff(abs(V)),false]).'
Z =
-4.50000 -1.50000 -2.50000 -1.20000 0.00000 1.20000 2.50000 1.50000 4.50000

[0.15, 0.15, 0, 0 ,0 ,0 ,0.15 ,0.15]
The vector has 8 elements, but has two pairs or adjacent identical non-zero values, so why is the output not sized 1x10 ?
If 1x10 is actually the correct size, then this would do what you want:
>> V = [0.15, 0.15, 0, 0 ,0 ,0 ,0.15 ,0.15];
>> Z = V;
>> Z(2,:) = 0;
>> X = [~diff(abs(V)),false] & V~=0;
>> Z = Z([true(size(V));X]).'
Z =
0.15000 0.00000 0.15000 0.00000 0.00000 0.00000 0.00000 0.15000 0.00000 0.15000
This gives Z with 10 elements. If you really want 9 elements, then you will have to explain the logic to me, of why one pair does NOT require a zero to be inserted (and which pair).
PS: these are not cell arrays, these are numeric arrays. Numeric arrays do not have cells, they have elements You can read about the different basic data classes here:
