Is there a way to tell the compiler to exclude the JVM if using compiler.build.StandaloneApplicationOptions?
I have an existing build script for a console application that compiles with the following command:
compiler.build.standaloneApplication(opts)
where opts is of the type:
compiler.build.StandaloneApplicationOptions
Is there a way to tell the runtime to exclude the JVM inside the opts argument so that it will load faster? I basically want to do the same thing as:
mcc -m -R -nojvm
Unfortunately, I don’t want to re-write this build script because it is a standard script we use.
Thanks in advance,

The best way to convert png to webp without losing quality?
Hi everyone,
I’m trying to convert a batch of PNG images to WebP format on my Windows PC, but I’m not sure where to start. I’m looking for a method that’s straightforward and ideally doesn’t require too much technical knowledge.
I’ve heard that tools like the Photos app or command-line utilities might work, but I’m not familiar with the process. Could someone please recommend the best way to convert png to webp without losing quality? If possible, I’d really appreciate a step-by-step guide or any tips that could make this easier for a beginner like me.
Thanks a lot for your help! Looking forward to your suggestions.

Please help! Savings for 2025
Hi everyone!
I could really use your help on this, so please bear with my explanation! Thank you so much for your time in advance. This may be a bit of a challenge, but I’m really at a loss as to what formulas are needed, what data is needed to make those formulas work – an ABSOLUTE loss!
I’ve attached a mock-up I’ve done that is similar to the real thing. It is one tab of a multi tab spreadsheet that is focused on finances for 2025 – this is the savings tab. During the course of 2025, there are some things that I need to save for, so I’ve added at the top some examples, with the target date, target to save and then I’ve worked out how many months I will have to save that (I’m paid on the 15th of the month and the entries from A17 help with this). It then gives a split out as to how much I would need to save each month if I wanted to achieve the target amount by the target date. Hope you’re still with me!
I then have an entry for each month, how much disposable income I have to save, how much to pay on each savings goal and then how much disposable income I have left after saving for them.
What I want is that each month it allocates the most money to whatever one I want to save for first (by date), then the next date etc. When one of the savings targets is then met by the date, the following month the extra money then goes into the next target savings goal. For example, if you look at savings goal 3) Car Repair, it wants £65.00 a month to achieve by the target date (15/10/25), but I only have £26.38 available each month. However, that is only until say May or July when the other savings goals are paid off, then I can put the extra money (that I’m not paying towards these) into 3) Car Repair, so it ends up still being paid off by the date, just it won’t end up being £65.00 each month, it’ll be a lower figure in the first number of months and then increase when the others are paid off.
I really hope this is somewhat understandable!! I want to be able to alter the target amounts, target dates, available to save money, and have everything auto adjust to try and work out a savings plan – what I need to put into the savings amount each month for that goal to try and get it paid off by the target date. If suddenly something changes, such as I have more disposable income or the savings goal is reduced, then the spreadsheet will all automatically update to those changes and then the plan (plan being the best word here) changes. If a savings plan cannot be achieved, as in there isn’t enough money available that month to cater for all of the “> Savings”, then it flags up and identifies this and tells me that more money is needed. I can then make some changes elsewhere and make sure there is extra available funds (if I need to!)
I really really hope that this is understandable and any advice anyone is able to give is appreciated so so much.
If you have any questions then please do contact me!
Thank you so much again.

How to connect a 6 DoF joint to a moving center of mass (by creating a moving frame) in Simscape Multibody
I am simulating the projectile motion of an ariel vehicle with its wing deployment in Simscape Multibody. The ariel vehicle has an initial velocity, which is provided by the State Target in 6 DoF joint. The 6DoF joint is connected to the CG location of the whole vehicle at its initial condition. During the projectile motion of the vehicle, the wing deployment occurs.
The CG location of the vehicle changes at every instant due to the wing deployment. I am measuring this distance using an Inertia Sensor. The whole process until this step works well.
My actual aim is to do a co-simulation between Simscape and a CFD solver. I created a Standalone FMU from the simscape model and provided to the CFD solver. From CFD solver I calculate the aerodynamic forces and moments based on new CG location at every time step and give as input to the simscape multibody model (FMU).
Current difficulty:
My current difficulty is on placing a joint on a moving center of mass (CG) in Simscape Multibody. In simscape, when we place a 6-DoF joint, the center of rotation is always on the joint connection point. In my case, this point is fixed at the initial CG location. Instead, I want to have a joint at the moving CG location. If I have a frame on the moving CG location, I can apply the aerodynamic forces from CFD (using 6 DoF joint) directly at that location. I tried to follow some related answers from https://www.mathworks.com/matlabcentral/answers/1576920-placing-a-joint-on-a-moving-center-of-mass-in-simscape-multibody?s_tid=answers_rc1-2_p2_MLT and https://www.mathworks.com/matlabcentral/answers/1851513-simscape-multibody-apply-forces-sense-velocity-of-global-center-of-mass to resolve this issue, but I could not succed.

Non Integer Meeting Counts for Custom Query
Hi Viva Insights Community,
We’ve built a custom query, the query is designed to identify meetings held on Friday afternoons. We’ve been running this query weekly, but when analyzing the results, we noticed that the number of meetings for some individuals on a given Friday is being reported with decimal values (e.g., 1.3333 or 0.666667).
Does anyone know why this happens? Could it be related to how the data is aggregated or a query setup issue?
Appreciate any insights!

How to update PID after system identification with closed loop PID Autotuner?
In the literature, system identification can be performed using various techniques like RLS, ARX, ARMAX, Kalman Filter, or frequency domain methods. In quadcopter systems, PX4 uses an autotune mode with the RLS method, and after that, GMVC law is applied to find optimal PID parameters. Similarly, Simulink has a ‘Closed-loop PID autotuner’ block.
What I’m confused about is the process of updating the PID parameters after system identification, which is typically done in a closed-loop setup. For example, let’s say I have an active PID with P: 3, I: 4, D: 2.8. If we use GMVC or another method to identify new PID parameters based on the closed-loop system response, how do we update these PID values?
Directly replacing the old parameters with the new ones seems problematic because the system identification itself was based on the current closed-loop response. I’m considering that we might need to combine the old and new PID parameters into a series configuration, which implies having two different PIDs in sequence. However, this doesn’t seem ideal.
Would it make more sense to extract the transfer function of the closed-loop system, remove the contribution of the current PID, and then apply the new PID parameters based on the open-loop transfer function by adding the old ones and test?In the literature, system identification can be performed using various techniques like RLS, ARX, ARMAX, Kalman Filter, or frequency domain methods.

of course i can add "If (x is large) and (y is small) then (Z is ‘…’)", but i cannot add "x+y+2", how can i do it?
thanks so much implement sugeno in fis MATLAB Answers — New Questions
Cannot locate a valid install area
Hello
I’m trying to run an app on MAC, the app was built in Matlab and MCR (Matlab runtime) is required. I went ahead and installed Matlab_Runtime_R2021a_maci64 and I’m getting the following error:
Do you have any idea? any advise on how to fix this problem?
Thanks,Hello

coupled differntial equation using ode45
I’m getting an error while solving this coupled differential equation usually the error is showing issues with vertical concatenation. here’s the equation i’m tring to solve with mu0 = exp(-T0) and Boundary conditions as : U(y = -1) = 0 and U(y= 1) = 0 and T0 = 0 at y = -1 and T0 = 1 at y = 1.
here’s my code:

% The velocity equation is:
% d/dy (mu0 * dU/dy) = G
