About the solution type in OOPs OnRamp course in Matlab
There is one particular course in Matlab called OOPs OnRamp which is really hard to solve even with the help of the solutions nearby. I feel that it is because of the file format. In that course, we are to type our solutions in different files and run them seperately and finally solve them which is really difficult for me and many of my friends. Is there any explanation for the course to solve? All the lessons in that course is hard to do.There is one particular course in Matlab called OOPs OnRamp which is really hard to solve even with the help of the solutions nearby.

tally scores over several sheets
I am trying to create a summary score sheet to find a High point winner. The program has an Entries sheet where names are entered and marked as to which ‘classes’ they are participating in. (there are 12 classes) Each class has it’s own sheet. The competitors receive a set of scores for each class which is totaled and sorted High to Low. Of a total of 30 competitors maybe 10 are in one class, they can enter several classes.
I want to create a summary of their scores. A summary page uses this formula (=IF(Entries!$A4<>””,Entries!B4,””) to copy their names to the summary. The problem is for ‘Class A’ when the scores are tallied and sorted, the total does not match the competitor input line anymore. I can total a score if I chose a specific cell (=’#1 (Saturday)’!T6) but it does not relate to that competitor… Is there a way to sort that out?

Error encountered in the Deep Signal Anomaly detector while running the official SIMULINK example
Hi all,
I am runnining this official Simulink example here: fault_localization in 3-phase power line.
I had a somewhat different circuit and thus I trained a new model following this guideline. However, after training my deep anamoly detector and while trying to apply this trained model to my detection model, I keep getting this error as shown in this screenshot:
Any suggestions on how to fix this? I’m pretty sure I used the
saveModel
command to save the parameters of my trained model. It looks like the model parameters file in the provided example works here, but mine wouldn’t work. I spent quite some time on this but still haven’t figured out a solution.Hi all,

Unexpected behavior resulting from the Three-Phase-Fault block in my simulated circuit (Simulink)
Hi all,
I am simulating a circuit with a 3-phase fault inserted as shown here:
My goal is to simulate the fault at different locations by varying the length of the Distributed Parameters Line blocks many many times, and then collect the 3-phase voltage + current data for training a deep neural network for fault localization. Thus, I used an external control signal to somewhat randomly switch on and off the three-phase-fault block as shown here:
Where SysModel is the one I just showed earlier.
However, the weird thing happens. The external control signal to the 3-phase-fault occurs at around 0.01 second (determined by the pulse generator and delay), and lasts for 0.01 seconds. But the resulting 3-phase voltage and currents in the Time Scope look like this:
this does not make sense because:
There is no transient resposne in the currents at all
The transient response in the voltages should die out shortly after 0.02, but somehow it automatically turns up again toward the end of the simulation.
Here is the time scope for the external control signal that’s going into the 3-phase-fault block (From "Composite Signal 1" in the previous screenshot):
In addition, I am using the following settings for the Distributed Parameters Line blocks:

Dissertation Footnotes
I need the numerical footnote reference to be a size 12 font in the body of the text and a size 10 font in the footnote at the bottom of the page. Right now, I insert the footnote at the end of the sentence and have to change each individual one to size 12. I am about to combine all of my individual chapters with over 1,000 footnotes. When I cut and paste it, I am concerned that I will need to go back and individually change every one of the numbers in the body back to size 12.
Since I will continue to produce scholarly work, I would like to know how to do set this up where these will display correctly. I am working in CMS/Turabian for the formatting of the dissertation.

Sharing data with a community
Hi all,
I’m an admin for a small group of volunteers in our community. As such, we’ve signed up for Microsoft’s non profit program.
I would like to accomplish the following: create a simple sharepoint site (document library?) in which members of my organisation can upload data (leaflets, promo material etc.). This data should be public available over the internet to everyone in our community, without the need for people in the community to sign in first.
Is there any way we can accomplish this?
Thanks for your answers 🙂

Rejected stereo image pairs in Stereo Camera Calibrator App
Hello all,
I’m trying to use the “Stereo Camera Calibrator App”.
I’m trying to import four pairs of images, but it only accepts one pair and rejects the other three. I followed the advice from the camera preparation page, but it didn’t do any good. I have no clue why it rejects most of the image pairs.
Please see the attached four images of each camera (left and right). The checkerboard size is 3 mm.
Thank you.Hello all,

Calculate the normal vector between two nodes in the space
Hi! I have two nodes A and B. These are positioned in space with the same value of X and Y but different Z. The normal in this case would be n=[0 0 1] (red plane parallel to the XY plane).
I would like to calculate the normal n ‘green’ in the case of nodes A and C. Is this possible?

NN = [A;C];
