Hello, I’m trying to do the QR decomposition using Gram Schmidt but I’m having problems because I can’t find the R matrix. Could you help me?

First of all I don’t want to use the reflection method. Only Gram-Schmidt.

So here’s the program for Gram-Schidt:

GS[A_] := Module[{u = {}, col, e = {}, ae, t},   col = Transpose[A];(* list with the column vectors of A *)   u = Append[u, col[[1]]];   e = AppendTo[e, u[[1]]/Norm[u[[1]]]];   For[i = 2, i <= Length[A], i++, ae = 0; t = 1;    While[t <= i - 1, ae = ae - (col[[i]].e[[t]])*e[[t]]; t++];    u = AppendTo[u, col[[i]] + ae];    e = Append[e, u[[i]]/Norm[u[[i]]]]]; {u, e}]

with this simple matrix:

B = {{1, 3, 1}, {2, 2, 1}, {3, 2, 3}};

gives

{{{1, 2, 3}, {29/14, 1/7, -(11/14)}, {14/69, -(49/69), 28/69}}, {{1/    Sqrt[14], Sqrt[2/7], 3/Sqrt[14]}, {29/Sqrt[966], Sqrt[2/    483], -(11/Sqrt[966])}, {2/Sqrt[69], -(7/Sqrt[69]), 4/Sqrt[69]}}}

Now the code for QR decomposition is:

QR[A_] := Module[{Ak, i, Q, R = {}, a = {}, col, k},   Ak = FullSimplify[GS[A]];   col = Transpose[A];(* list with the column vectors of A *)   Q = MatrixForm[Transpose[Ak[[2]]]];   For[i = 1, i <= Length[Ak[[2]]], i++, a = {}; k == 1;    While[k <= Length[col], a = AppendTo[a, col[[k]]. Ak[[2]][[i]]];      k++];     R = AppendTo[R, a]];   R = UpperTriangularize[R]; {Q, R}]

but I can’t find matrix R, once it’s giving me a list like this{{},{},{}} and I’m stuck. Please help me.Thanks!

Hello i have this code thats not written out in the write form can someone rearrange it for me quickly Thank you [closed]

Cipher suite is different in “client hello” for the same code running on different platforms

I’m facing a “Alert: handshake failure (40)” error when trying to establish a TLS connection. The error only happens when I run the same application on cloud, it works when I run the application on HPG8 server. OS is the same Redhat 7. By checking into the traces, I found that the cipher suite in “client hello” is much less in the error case than the worked case, and the cipher suite that TLS server supported is just missed in the “client hello” of the error case. I want to know what will impact the cipher suite that contains in the “client hello”?

The openssl version is the same (1.1.1d) for both cases, Redhat version has small difference. TLS1.2 is used. The key file and cert file are also the same.

In the code, I’m using SSL_set_cipher_list to set the cipher string as “ALL:!DH:!EXP:!RC4:@STRENGTH”. 

SSL_set_cipher_list(ssl, "ALL:!DH:!EXP:!RC4:@STRENGTH");

I also checked the source code of openssl, but didn’t find much clue.

TCP communication in between the TLS1.2 client and server hello?

I’m building an IoT project using AWS. All works as intended, however I’ve done some wireshark analysis of a message being published to the cloud: The TCP handshake is as expected, and all the elements of the TLS handshake are as expected. However, between the client hello, and the server hello there are three exchanges of TCP packets: Should see it in the picture – Any idea what these TCP packets contain? enter image description here

No Client Hello w/ SNI when accessing website’s subdomain via link

I noticed this while testing SNI-based HTTPS filtering for fun.

mail.yahoo.com is blocked when accessed directly. It is not blocked if you login to your Yahoo account and access mail.yahoo.com via the “Mail” link. I ran a packet capture and see there are no Client Hello messages with the mail.yahoo.com name in the SNI extension field when I click the “Mail” link.

My assumption is that the client is somehow re-using the same connection since the *.yahoo.com certificate is valid for both domains. Anybody with some deeper knowledge of TLS able to clarify what’s going on or able to point me in direction of some documentation?

Also, if that’s the case, then why does Chrome send a Client Hello w/ Google subdomains when attempting similar tests via accounts.google.com?

NOTE: I’m blocking UDP/80 and UDP/443, so QUIC should not be influencing my results. Also, I use deep inspection in my day-to-day, so please no responses telling me to stop using SNI-filtering.

Server sending RST after Client Hello

We are facing intermittent TLS handshake issue while connecting from a C++ (Openssl 1.0.2e) client to a Java Server (Java 7). The issue is observed on load test after having around 100 session sending concurent requests, that too on linux platform. Server is sending RST message immediately after “Client Hello” message. On client side the SSL_CTX object is created with TLSv1_2_client_method(). On server side the context instance is created by invoking SSLContext.getInstance(“TLSv1.2”). Also we are limiting the enbled protocol to TLSv1.2 on server side. Whenever this issue is observed we have noticed that Client Hello Protocol on Wireshark as “TLSv1”, in all other cases(SUCCESS) the Client Hello Protocol is displayed as TLSv1.2.

Also I understand the Handshake layer version number is important and any TLS1.2 compliant server MUST accept any value {03,XX} as the record layer version number for ClientHello as per RFC5246. But whenever the failuere is observed, record layer is “TLSv1 Record Layer: Handshake Protocol: Client Hello”. In the case of successful handshake the record layer is “TLSv1.2 Record Layer: Handshake Protocol: Client Hello”. The client hello message for both the cases are given below, note that the cipher suites and signature algorithm are same in both the cases.

When this issue occurs (ie. SSL_do_handshake() fails) SSL_get_error returns SSL_ERROR_SYSCALL, but ERR_get_error() returns 0. We are calling these two methods immediately after SSL_do_handshake().

Appreciate your assistance as this is going for some time.
