datasampled datatable

Hello, How to sample data for every 40 ms. As my data is quite big (75000ms)I'd like to display only every 40th sample of my data in a form of simple table (1st row :ms), second row:values)

Thanks for your help.

Just do what you did and then say

y = y(1:40:end);

By the way, that (75,000 elements) is a long, long way from being a "quite big" matrix.

MATLAB: How to convert decimal values to a fix length of binary numbers

Hi there,

you can easily use

dec2bin(n,p)

where n is your decimal number and p is your desired length (for your question is 10)

dec2bin(9,10)
ans =
    '0000001001'

but you need to becareful that this is not a number (it's string), if you want to convert it to a number you need too use this one instead

dec2bin(9,10)-'0'

hope this works for you.

MATLAB: Extract specific line with nubers

Hey Ali,

I hardly recommend you to format your data as a table.

For extracting a specific Line use find():

For Example:

Energy R Z Th Result Rel Error

1.000E+36 5.000 6.750 0.500 2.14157E-17 9.41189E-01

Energy=1;
R=1;
Z=1;
Th=1;
Result=2;
RelError=3;
%myTable is your readIn Data
YourLine=find(myTable{:,1}==Energy&myTable{:,2}==R&myTable{:,3}==Z&myTable{:,4}==Th,&myTable{:,5}==Result&...
myTable{:,6}==RelError);
if(isempty(YourLine)==0)%just to prevent crashes if a line can not be found
    %do something further
end
