MATLAB: How to get selected value in a vector

data selection

I have temperature data of about 120 days and I want to select temperature of 1,12,24,36,48,60,72,84,96,108 and 120th day, How to select it?

When I am trying by this

for x=1:12:120

it is taking for 1, 13, 25 and so on

if I take x==linspace(0,120,11)

but I dont have any value at 0 i.e 0th day dont exist, it starts frrom 1st day.

Pls Help

for x = [1 12:12:120]

MATLAB: Truncating rows from a matrix

Mohammad, not knowing exactly how your data is organized you could follow this path:

 data  = eye(12);         % as an example I use a 12-by-12 unity matrix
 dataC = cell2mat(mat2cell(data,4*ones(1,3),12).');
 dataC([2 3],:) = [];     % replace [2 3] by [10 15 20 90 120]
 dataR = cell2mat(mat2cell(dataC,2,12*ones(1,3)).');

Using the mat2cell command, first reshape the matrix from a 23*144-by-10 to a 144-by-23*10. Eliminate the rows and convert back to a 23*139-by-10. In other words try

 dataC = cell2mat(mat2cell(data,144*ones(1,23),10).');
 dataC([10 15 20 90 120],:) = [];
 dataR = cell2mat(mat2cell(dataC,139,10*ones(1,23)).');

%Still not getting the exact question, are you looking for this one?

%x1-Min voltage value x2-Max voltage value

    clc;clear;close all;
    v=randi([0 1], 21 , 21);
    for i=1:120
          x=(0.12-0.001).*rand(1,1) + 0.001;
          v(:,:)=x
          pause(0.001);
     end
