I want to extract data from one table and move into another from specific location in the first table.

I have created a code to compute the centered moving standard deviation of a data in a table, now I want to get the data starting from the 4th position to the last position with an increment of 5 between the positions.

I wrote a code which is extracting the st dev from the table and then I created a table of the length of the number of data points I want to extract from the second table, but when I tried to put it into the second table the out was just zeros.

Please help!

clear;
clc
close all;
T = readtable('NSEI1.csv');

Error using readtable
Unable to find or open 'NSEI1.csv'. Check the path and filename or file permissions.

T.Date = datetime(T.Date,'Format','dd-MM-uuuu');
M = movstd(T.Open,[3 1]); 
g=length(M)
f=round((g/5))+1;
h = zeros(f,1); 
for i=4:5:length(g)
  h=[h;M(i)];
end
disp(h);

The output of this is just a table of zeros please help!

% M = movstd(T.Open,[3 1]); 
M=[1:100] % just so I can test it without your CSV
g=length(M)
f=round((g/5))+1;
h=M(4:5:length(M))
