MATLAB: Subtracting and saving in an array

My data looks like this, where column headers are No and Time,respectively.
    '1'      '0.000000000' 
    '2'      '0.100244000' 
    '3'      '0.199460000' 
    '4'      '0.299659000' 
    '5'      '0.399856000' 
    '6'      '0.499070000' 
     .
     .
    '50'     '4.893317000' 
    '51'     '4.993553000' 
    '53'     '5.095700000' 
    '55'     '5.194844000' 
    '57'     '5.295069000'
How to find:
  1. I want to find the values for (0.000000000 – 0.100244000), (0.100244000 – 0.199460000) and write the answers in a separate array.(eg:No, Time, and Time difference).
  2. In the 1st column,after value 51, next value is 53. I want to count how many values have been jumped like that instead of following a sequence as 51,52,53…

Based on the text file that you uploaded, I altered my first answer to read all of the columns in your data:
fid  = fopen('temp.txt', 'r');
data = textscan(fid, '%d%f%s%s%s%d%s', 'MultipleDelimsAsOne',true, 'HeaderLines',1);
fclose(fid);
jumps = sum(abs(diff(data{1})>1));
timeD = diff(data{2});
After placing this in a script and running it, I can confirm that it correctly extracts the data from your sample data file:
>> jumps
jumps =
     1
>> data{1}
ans =
           1
           2
           3
           4
           5
           7
           8
           9
          10
          11
          12
          13
          14
          15
Note that I altered your text file by removing data row six to provide a jump in the first column, which it seems you want to detect, otherwise it is identical to what you uploaded earlier.
