@robjohn Oi! Now it makes sense!! Thanks a lot!

Sohaib

Apr 22, 2014 16:29

@robjohn I saw this in a research paper. Doesnt seem to make sense 0.o

Sohaib

Apr 22, 2014 16:28

@robjohn Okay. Also is mod(A,1) always 0?

Sohaib

Apr 22, 2014 16:25

and mod(A,b)

Sohaib

Apr 22, 2014 16:25

Sohaib

Apr 22, 2014 16:25

Is there a difference between A%B and A mod B

Thanks got it.

Sohaib

Mar 31, 2014 18:20

Ohh nope.

Sohaib

Mar 31, 2014 18:19

What do you mean by $?

Sohaib

Mar 31, 2014 18:17

@ParthKohli No prob :)

Sohaib

Mar 31, 2014 18:15

@ParthKohli Okay?

Sohaib

Mar 31, 2014 18:11

@ParthKohli I didnt understand how the answer came out to be 11.

Sohaib

Mar 31, 2014 18:10

*on

Sohaib

Mar 31, 2014 18:10

@ParthKohli In his book i=on cryptography he calculates (-1/2)mod23 as 11

Sohaib

Mar 31, 2014 18:09

william stalling seems to disagree :P

Sohaib

Mar 31, 2014 18:09

@ParthKohli okay

Sohaib

Mar 31, 2014 18:08

@ParthKohli Im talking of modulus division sorry. As in computer science.

Sohaib

Mar 31, 2014 18:07

what should be the answer to this?

Sohaib

Mar 31, 2014 18:07

@ParthKohli Say (-1/2)mod23

Sohaib

Mar 31, 2014 18:06

Hello.
how do we calculate the modulus in case of decimal numbers?

How do we calculate the covariance matrix?

Sohaib I

Nov 10, 2013 16:55

I got a question

Sohaib I

Nov 10, 2013 16:54

Hello

Sohaib I

Nov 6, 2013 20:28

My 60 x 120 matrix has currently elements from -1 to 1 with two rows columns as completely zeroes.
If I scale it between 0 and 2 will it have an impact on my overall result?

Sohaib I

Nov 6, 2013 20:26

@Zibadawa Thanks. I found another method using cholesky factorization that works.
But now an error pops up saying matrix must be positive definitive.

See this equation which represents the Bhattacharyya Distance

Sohaib I

Sohaib I

Nov 6, 2013 19:03

@Zibadwa Many statistical methods require me to use inverse like the Mahalanobis Distance. How should I proceed in such cases?

Can we find the inverse of non square matrices

Got it. Thanks.

Sohaib

Mar 31, 2014 18:18

@Gilles I do not understand how the answer came out to be that :(

Sohaib

Mar 31, 2014 18:16

@Gilles would the answer be 11?

Sohaib

Mar 31, 2014 18:15

Didnt get you
I mean to say like 24 mod 23 = 1

Sohaib

Mar 31, 2014 18:13

Where mod means modulus division

Sohaib

Mar 31, 2014 18:13

Hello.
How do we calculate the (-1/2)mod23 ?
