Hermitian Adjoint of a Matrix using Python
In this video lecture that follows on from the pen-and-paper lecture on the Hermitian adjoint of a complex-valued matrix, I show how easy it is to calculate the Hermitian adjoint of a matrix using symbolic Python. I also show you how to calculate the Hermitian adjoint of matrix-vector multiplication and the Hermitian adjoint of matrix-matrix multilication.

In this video I explore complex-valued vector. These are vectors that have complex numbers as elements. After introducing complex vectors I look at scalar-vector multiplication, vector addition and subtraction, the Hermitian adjoint of a complex vector (which is the complex transpose), the dot product, and finally the norm of a complex vector.

OMG after more 10 hours I did it. You are best, THANK YOU!!!
thanks bro really helpful
Yay! Dr. Juan Klopper I'm a fan!
Thanks very much for this tutorial, it helped me a lot to start using Pluto. I have been using a slightly different workflow, however, and I am wondering if it accomplishes the same thing as activating the environment from within the Pluto notebook. What I do is in the Terminal (I am using a Mac) I start Julia then go to Pkg by typing right-square bracket. At the Pkg prompt I activate the environment I have created that contains all of the packages I will use (DataFrames, VegaLite, etc.). I then exit Pkg (using Cntrl+C) and when I get back to the Julia prompt I type using Pluto and then Pluto.run(). That opens Pluto and then I start creating my notebook. Also, I don't save the Pluto notebook in the folder named for the environment but instead I save it in a folder one folder up. I don't think that makes a difference, though. But I am trying to confirm that it is equivalent to what you are doing in the video. Thanks again for your help.
Change the 't' to an 'x' and you get "the Calculus of Variations"
Dr. Klopper, this is great content. Thank you very much for sharing. I have many questions about ANCOVA answered from watching this video.
This is beautiful maths indeed. Thank you.
I can't thank you enough for this video series, it's so beginner friendly. Truly grateful
This is a great video saving my life 😃😃 Thank you sir
Excellent explanation!
Thank you very much Dr. Klopper 🙏🏽
Thank you very much for this lecture
Thank you so much sir for this video. Beautifully explained.
really the dumbiest man to ever exist , putting the preview of the next video on the area with the formula
is there any way to acess pdf files and notebooks for learning and practice in 2023
OMG! I'll try this on my Plotly project right away Thanks a lot and greetings from Brazil
Thank you so much for this linear regression based view of ANOVA professor. It helped me a lot!!
Dr Klopper , is it possible to activate the environment on an offline computer and keep all the packages working ? If so , how can it be done please ?
Yes. If you create an environment on your local system (with a project.toml file) you can use Pkg.activate(<path to environment toml file>) at the start of the notebook. Remember to include using Pkg before activating the environment. I do have a video showing how to create Julia environments.
if you can do more videos to cover more on linear algebra and python, will be great, good teachers are rare and for sure you are good thanks
Thanks for this video
Dankie Dr
Can u make also plot a graph of the soln.? My graph deviates significantly at higher values of x😢
I was able to get rid of my hypothyroidism with the help of #drobaedo herbal supplement continue saving life
very good lecture!!
Great !
The tie though.
Thanks a lot sir.
Most welcome. My pleasure.
This really helped me, great explanation. Thank you
Glad to hear it Ali!
What a vivid explanation! From now on I am your student. Compares to videos of Lagrangian equation derivation I have seen on RUclips, you are the best.
You're very welcome! Thank you for the kind words.
Your explanation is the best one so far sir. Thanks many many times. Please upload videos on port hamiltonian systems if it is possible for you.
Thank you very much for the kind words Nikhil.
Very useful video for me, thank you!
Glad to hear that!
thank you sir!
You are welcome Robert!
Why is laproscopic cholecystectomy indicated when mild acute pancreatitis has resolved and an US doesn't show any abnormalities?
great video
Prof doing an incredibly outstanding job of explaining the derivation, sorry for mistyping earlier.
This is Amazing....May you live long sire your brians are great and exceptional. Thanks for this.
Thank you sir.
Very informative! Thank you! Would like to see more of these Foundational Level videos! I do however have one question: How does the output differ from an ANOVA? Or is it rather a stepwise explanation of what an Anova package will do under the covers?
Hi Flippie. Thank you for the compliment and the comment. Are you considering simply the difference between calculating a t-statistic and an F-ratio rather than simulating results through reassignment?
Thank you very much for this, sir. Very useful and helpful
You are welcome AJ.
I am currently 3 months postpartum and dealing with hyperthyroid, I hope it is just postpartum and will go away rather than permanent. 😕
Can you use rk4 for second order coupled PDE?
Hello Juan, Thank you for the video. I was wondering if you could help me with the equation below to find the voltage drop in a pipe of certain length. The actual equation is similar to the one below: Voltage drop = upper limit X, lower limit S of the integral of current(x) multiplied by lineal resistance (x)dx Values are as below: Upper limit X= 4269 meters Lower limit S =0 meters Current measured in the pipe= 2.65 Amps Lineal resistance of the pipe = 109 Micro-ohm/meter Voltage drop in mV = ? I have spent a lot of time trying to solve this and I am hoping I can get some guidance from your capable hands.
Sir, how to calculate the error
Can I please know how do you give the labels to the model in your tutorial ruclips.net/video/n4mxwSAWvo8/видео.html
Hashimoto is one reason
Great stuff
Thanks Bayanda.
incredible nice video
Thank you very much!
What kinda scam is this? The title says inverse matrix but there's nothing on that
Thanks. Excellent tutorials!!!
Glad you like them!
great stuff dr. how can i access the notebook?
