## Calculating then sorting by Highest to Lowest Average for Case Data in Excel

Hi!

I’m hoping someone may be able to assist with something I am trying to achieve in excel with regards to calculating the average case resolution time on case data for a set of customers, so I can then sort my spreadsheet from highest to lowest to identify which customer’s cases are taking the longest to resolve.

I’ve attached a very simplified example of what the spreadsheet looks like – but the actual data I’m working with contains several hundred customers with over 4000 cases (rows) meaning I need to find a way to automate this through a formula of some sort.

Any help would be appreciated 🙂

## System of nonliner equations with symbolic variables

Hi there,

I would like to ask you how to solve a system of nonlinear equations while using symbolic variables.

I have two equations that I need to solve:

eqT = 10*lamT^13*lamZ^13 – 10/lamT^13 – 10*lamT^2*lamZ

eqZ = 10*lamT^13*lamZ^13 – 10/lamZ^13 – 5*lamT^2*lamZ

where lamT and lamZ are symbolic.

I was trying to search for it and most times I have found to use matlabFunction and fsolve. But it doesn’t work for me. Probably I understand it wrong or maybe I am doing another mistake.

fun = matlabFunction(eqT, eqZ)

eqsol = fsolve(fun,[1 1])

Can you please help me and explain me what I am doing wrong.

Thank you very much

P.S.: it is not possible not to use symbolic variables. They are used for some derivations before. Also it is not possible to rewrite the equations manually because they are to be solved many times in for cycle with different constants.Hi there,

## Solving symbolic array.

I am working with symbolic vector of 1xN size. The vector contains N eqations in the from of

X == a + b + c

Y == X*(d + e + f)

Z == Y + X

I am suing subs to substitute the coefficients a b c d e f with numeric values. The result is in the form of

X == g

Y ==X*h

Z == Y +X

It sould be quite straigh forward to solve for Z since all variables are numeric, but for crying out loud I cannot make matlab to solve for Z.

Any ideas?I am working with symbolic vector of 1xN size. The vector contains N eqations in the from of

## Impossible to list rows in power automate

Hello,

I’m a beginner on power automaton and I’m facing a case I can’t solve.

The 1st step of my flow is to create an xls file on sharepoint with PBI as data source.

The file is saved in a folder under the name Docusign.xls.

There’s nothing to stop me dropping it each time under a different name, Docusign_date.xls, if necessary to solve my problem.

I can’t use list rows to obtain the columns contained in this excel file. I’ve tried the following method:

1) Send the file always under the same name and move it to a folder once processed because sharepoint prevents the creation of a file with the same name in the same folder.

When I rerun the stream, I lose the path (which is hard-coded) to the file in List rows.

2) Send the file under a different name, but I don’t know how to recover the columns of my new file in list rows.

In short, if the path is not hard-coded, it won’t work. And since it’s a new file every time I run a feed, I don’t know how to do it.

I thought of an office script that would compare the 2 files (id) and write the new lines in file 2. This file 2 would always stay in the same place. But I don’t know if it’s possible

Thanks in advance for your help

I have completed the account recovery form, but I haven’t heard anything after 24 hours.

I recently had to reset my phone and forgot my password for my Outlook account. The Authenticator doesn’t work due to the reset. I’ve filled out the form for account recovery several times. The first few times I immediately received mail that I had to add information. I did that and it said it would be reviewed within 24 hours. When will I know my account can be recovered?

## Ncorr post Fail help

Hello Friends,

I apologize in advance if I skip some protocol to post my problem, but I am new to matlab and the forum. After long attempts to make Ncorr_Post run, I decided to consult by this means.

To summarize, I have already processed images with the add on Ncorr, I managed to realize that even the results obtained were saved correctly, generating some workspace with the field of displacement and deformations for each image that allow plotting graphically as seen in the ncorr generally. But, what I am really interested in is not the displacement field itself, but to extract the linear displacement from one point to another (that is, a column with the displacement data of the material, to be able to compare with the displacement delivered by the testing machine), the Ncorr_Post extension does exactly this by the name of "virtual extensometer". The problem is that when I load the data from the Ncorr and the .mat file that it generates, it gives me an error, if I load the .mat file the problem is to recognize the dimension of the array and gives the following:

Index exceeds matrix dimensions.

Error in calculateOtherQuantities (line 3)

I don’t know if I am using Ncorr_Post wrong, but I have already tried with all the versions, even Ncorr. The only thing that I had to do was to try other versions of matlab, but I don’t know if this will work.

I hope you can help me to solve this, I would be deeply grateful.

Questions:

Why are the weights and biases not updating, and why do the biases remain zero?

How can I ensure that the gradients computed are correct and being applied effectively?

Are there any specific settings or modifications I should consider to resolve this issue?

## How To Remove Copilot Preview?

Well I updated my system to 23H2 and Copilot Preview keeps appearing now on my taskbar. Even after removing the icon it keeps returning.

Now from what I can tell Copilot is not running but it is in Program FileWindowsApps which I cannot access or change permissions. Now my question is, can I delete all to Copilot files because it dose not show up in any of my uninstallers. I know if I delete them I most likely will f^#* myself over. Or do I have to revert back to 22H2? I found all the files using Everything. Here’s a pic of some of the files.

## How to delete an undeletable file?

My computer is running Windows 11 23H2 and I’ve got a file created by 7Zip located in C:Temp (my C: drive is a Samsung 990 Pro SSD) where 7Zip crashed during the process of zipping files and now that file appears to be unable to be deleted. With Explorer run as administrator the file appears in the C:Temp directory however when I attempt to delete it I get the message “Could not find this item” and “This is no longer located in C:Temp. Verify the items location and try again”. I’ve tried starting in safe mode with the same results, the file appears in File Explorer or in a command prompt using a dir command but attempts to delete it always come back with “The file is no longer located in etc etc”. I’ve tried running “chkdsk /f” on my C: drive and then retrying both safe mode and normal startup and I can’t delete that file (it’s the only file in the directory) and I can’t delete or rename the C:Temp directory itself so how can I fix this problem?

## Intune – disable Windows Hello

I have a goal:

1. Disable Windows Hello for Business without impacting current users on EntraID via Intune,

2. Configure password sync on the Okta site and Entra ID and MDM device

What could be the way to disable PIN (for onboarded devices) and switch only to a password on endpoints? the password must be synchronized with Okta in both directions.

Thank you,

## iterate over a vector in a for loop
