delaunay function on raspberry pi?
Hello all,
I am trying to convert my code so it can run on a raspberry pi. However, part of my code is a map generator which uses the delaunay function to create a triangulation as follows:
(…)
x = x(:);
y = y(:);
z = z(:);
faces = delaunay(x, y);
randomMap = triangulation(faces, x, y, z);
end
Matlab Coder says it cannot convert the delaunay function. Is there any other function I can use to port this? I have already tried using ‘delaunayTriangulation’ or ‘alphashape’ instead, and tried to directly call ‘qhull’, but neither of these work. And since the delaunay function is built-in, I cannot look at the source code to fix this issue either and I do not know enough about the implementation to implement it from scratch.
Any help is appreciated!Hello all,

Saving image with high resolution
Hi,
I use this line of code to save my figure as .png : print(name,’-dpng’,’-r0′),
but i get a bad resolution picture bespite that the figure in matlab is good. I tried print(name,’-dpng’,’-r500′), but nothing changed.
How can i save figure as .png but with the same quality as the matlab figure?

Try to set a date on my cell and an data validation error appears
I’ve been trying to re-make a very simple Task Tracker that I had made on Google Sheets to Excel, and most fuctions work except the one to insert the Due Date of the Assigment. It opens the calendar and the rest of the Assigments that I imported seem to be working well, but when I try to add a new date, this error appears. I don’t understand why, since the Data Validation formulas are only supposed to work on the Course and Type columns. Please help me, I just wanted to be a responsible student.

Create Excel Chart with multiple series each with 2 data points
Hello,
I’m trying to create a chart in Excel with several straight lines composed with 2 data points each.
Each costumer has a sell date and sell value, and a purchase date and purchase value. Dates are in the X axis.
I just want that for each customer there is a straight line between sell and purchase value, on their respective dates, for each of the customers.
Is it possible?
I’ve attached an example file here.
Thanks in advance.

Reduce Outlook mailbox size while keeping email messages and attachments (and access)
My work email is “Microsoft 365 Apps for business” account, and I’m getting a warning “Your mailbox is almost full”.
I’ve read I basically have four options:
Enable Online Archive.
Increase the mailbox size.
Move messages to a PST.
Third-party email archive solutions.
I would like to manually create a local PST backup. I found this page here: Archive items manually (Outlook for Microsoft 365 Outlook 2021 Outlook 2019 Outlook 2016)
I completed the listed steps… now what? I don’t see any change in the Mailbox size. I didn’t see Outlook “do anything”.

shape has NaN vertices when adding new shapes to the aggregate shape encloses a void; error assigning shape to antenna
I am creating a PCB antenna pattern adding together copper Polygons and rectangles to make the PCB trace pattern. The copper traces short back on themself forming a region with voids in it.

When I show the copper it looks right (needs a little cleanup, but OK).
When I show or mesh the antenna it throws a triangulation error.

Intune scope tags

Created scope tag 1 which is assigned to admin1 (role – can read and write compliance policies, read and delete devices) (No other roles assigned)
Created scope tag 2 not assigned to any admin
Created compliance policy and removed the default scope tag and added scope tag2. My issue is, still admin 1 was able to read and write this compliance policy. Why this is happening and Am I doing something wrong?

Maybe Complex! Dynamic Array Query
I have an input sheet with staff salaries – and starting dates etc to pull in monthly salary costs for forecasting. But also want a ‘profile’ to enable a user to input a revised amount (Usually upward) during the course of the next 2 years from the start of current year. These will be used to override the default amount on the calc sheet
Calc sheet has all the breakdowns of everything. But I am trying now to incorporate the profile from the Input sheet into my basic monthly salary amounts. Looking for something like this. Ignore the combining with default values as this is straightforward. But I need the array of override values as below
I thought this would be quite easy but it seems not. As the periods will change from monthly to 3 monthly, one needs to sum based on dates. I have the start and end of period at the top so can do that. But the array of periods on the calc sheet does not match that on the input sheet which will just allow for 2 years of overrides, after which, simple inflation will kick in. Can’t really forecast salary increases going out more than 2 year and for new starts the default value (not shown here) will be used with a starting date. So this will only be used for changes during the immediate forecast period.
A simple sumifs does actually work for a single row but I want to create a full 2D array.
=SUMIFS(Inputs!$N$72:$AJ$72,Inputs!$N$71#,”>=”&L3#,Inputs!$N$71#,”<“& L4#)
Tried sumproduct also and used MAP function to map the starting ending dates of the periods
=MAP(L3#,L4#,LAMBDA(x,y,SUMPRODUCT(Inputs!$N$72:$AJ$72,(Inputs!$N$71#>=x)*(Inputs!$N$71#<y))))
L3 has the array of period start dates and L4 has the period end dates (Calc sheet). $N72:$AJ$72 holds the range of salaries for the profile and N71 has the header dates for the profile (Inputs sheet). This works fine as does a simpler Sumifs without the need to MAP. BUT. If I change the range of $N72:$AJ$72 to contain more than one row, I get a calc error. So fine on a row by row but can’t get it all in a single 2D array.
I tried ByRow in conjunction but that fails. Seems I can’t combine ByRow with another lambda function say from MAP or such. I also tried using a Reduce with VSTACK. One problem I see is that the array of dates on the profile is not the same as that on the Calc sheet period start & end dates and I can’t see how to align these in a clever way. Its not as easy as just mapping as the profile dates will always be in months but the Calc sheet is dynamic and the current year and forecast years can be set to 1,3,6 or 12 months. I even tried creating a THUNK for one of the lambda functions. But always get the calc error Because only sumifs actually seems to work with 2 dynamic ranges of different sizes, but I can’t use an input array with Sumifs (only a range – but it also deoesnt seem to work with BYROW) and Sumproduct needs me to use a MAP function (or similar) to match the date criteria in one range (actually in 2) to the criteria range of the profile, I can’t see how to avoid double nested lambdas. I was surprised that the ByRow didn’t work as a wrapper around the map and sumproduct (Or sumifs)
Anyhow, I know there are so many super smart people out there, it is probably not that hard but for me, I’ve run out of options to try. I even considered a matrix multiplication but couldn’t get my head around that either!! I’m sure there is a solution using that.
PS. My attached sheet doesn’t use the same refs as described above. I put it together to illustrate the issues. Just took a camera pic and laid it roughly on top of the cells so that the refs – starting ones on some do actually reflect the above.

Another, hopefully quick, Dynamic Array question
With a 2D array I wanted to replace any blank values on a row with the previous value. I found this which sort of worked. =SCAN(0, N72:AJ74, LAMBDA(a,v, IF(v=””,a,v)))
However, the accumulator value is carried forward to the next row so if there is a value at the end of the previous row, it is carried forward to the next row as SCAN just works its way through the array. I want to treat each row independently so that there is nothing carried forward to the next row.
I tried with ByRow but this caused a calc error. Couldn’t find a way to ‘get’ the row number or to determine the row had changed and thus be able to set a to 0. Or, to get ByRow to work which would have been the easiest.
This could apply to the MAP function too as getting the row and column index could help determine a new column or row
