Exacting a constant range/window of values from a matrix (skipping one cell each time).

Hi all,

I have a variable of values, X (1000 x 1) and want to create a separate variable, Y which is made up from values 1:24, skip one cell, then the next 24 values, skip one cell etc etc. until a certain value or the end of the matrix.

I feel like it should be reltively simple but just can't seem to quite get it right. Any help would be much appreciated.

Thanks in advance.

data=rand(1000,1);
data(25:25:1000)=[];
temp=length(data)/24;
cell_data=mat2cell(data,24*ones(1,temp))

cell_data = 40×1 cell array
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}
    {24×1 double}

Each cell element consist of 24x1 values, the good way to handle multiple array is using cell array, as shown in the code.

As per my understanding you want to skip every 25th value of a matrix.

I will try to explain it using an example below .

A=1:1000;
  B=A'

B = 1000×1

1 2 3 4 5 6 7 8 9 10

  for i=1:38
  B(i*25)=[];
  end
  output=B

output = 962×1

1 2 3 4 5 6 7 8 9 10
