AMD vs Intel and Single-Core vs Multi-core CPU Performance Selection for Simulink Speed
I’m a grad student who frequently does power electronics simulations in Simulink. I am thinking of getting a new PC with 32 GB RAM (5600 MHz) and need to select the CPU. I’ve stumbled upon supposedly good options, such as the Intel i9-14900K (or i7-14700F if I go for significantly cheaper), and the AMD Ryzen 7 9800X3D. Which will be faster for Simulink simulations? Does the fact that the i9 has 24 cores vs the Ryzen 7’s 8 cores make a big difference, or is Simulink, by default, bottlenecked by single-core performance?
I read that the Ryzen 7 9800X3D has higher single-core performance, but the i9-14900K will have better multicore performance and is favourable if I ran multiple simulations at once or used parallel computing. However, the parallel computing toolbox seems difficult to use, so I don’t know if I’d like to amend all of my simulation practices to adhere to it.
Please don’t suggest making my simulations different or optimized; I understand that that will make a great difference in simulation speed. Also, I’m sorry if my lack of computer hardware knowledge is showing!I’m a grad student who frequently does power electronics simulations in Simulink.

Can I create an alias for timetable signals viewed with Signal Analyzer in Signal Processing Toolbox R2025b?
I am currently using Signal Analyzer in Signal Processing Toolbox R2025b to view signals from a timetable. Signals from timetable columns display as "<TimetableName>.<ColumnName>".

How to move a 3D volume in 6D (3 Translations and 3 Rotations)
Hello everyone,
I am simulating a CT volume that includes a couple of different structures using the "createSyntheticSkullCT" function. After that, I generate X-ray projections from the CT volume.
My goal is to move this CT volume in 6D, which includes translation in millimeters (X, Y, Z) and rotation in degrees (roll, pitch, yaw). To achieve this, I defined a function called "applyRigidTransform3D" in code 1 and "rigidTransform6D" in code 2 for the 6D movements, but I am not sure if this function is working correctly.
I would greatly appreciate any insights or suggestions regarding this code. Is my simulation realistic? If not, which parts contain errors? I would also welcome any recommended validation or sanity checks.
I have attached the MATLAB codes (Code1.m and Code2.m) below for reference.

Trouble with Interp2
I am trying to use interp2 to look up values on in a table. I think that the problem is posed correctly (though obviously it is not), but all I get back is that the:
Error using interp2>makegriddedinterp (line 230)
Input grid is not a valid MESHGRID.
Error in interp2 (line 134)
F = makegriddedinterp(X, Y, V, method,extrap);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in LYNX_reflectivity_test_2 (line 61)
interp2(ang_mesh,ener_mesh,Refl,1,1000)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The code is below. The first step is to create a table of reflectivies as a function of angle and energy, interpolate that table line by line to create a finer grid in energy, and then test that the meshgrid works. That is where is fails, and I just can’t see what the problem is with the 2 interp2 statements at the bottom.
Thanks

interp2(ang_mesh,ener_mesh,Refl,1,1000)
interp2(ang_mesh,ener_mesh,Refl,2.6,10000) I am trying to use interp2 to look up values on in a table. I think that the problem is posed correctly (though obviously it is not), but all I get back is that the:
Error using interp2>makegriddedinterp (line 230)
Input grid is not a valid MESHGRID.
Error in interp2 (line 134)
F = makegriddedinterp(X, Y, V, method,extrap);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error in LYNX_reflectivity_test_2 (line 61)
interp2(ang_mesh,ener_mesh,Refl,1,1000)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The code is below. The first step is to create a table of reflectivies as a function of angle and energy, interpolate that table line by line to create a finer grid in energy, and then test that the meshgrid works. That is where is fails, and I just can’t see what the problem is with the 2 interp2 statements at the bottom.
Thanks
Peter

Peak Finder / Bandpass Filter errors on SimElectrical

2) My bandpass filter (attached to my sine wave output) is giving me an error as follows:
Output port 1 of ‘Circuit/Bandpass Filter’ is a one dimensional vector with 1 elements.’
Any help would be appreciated,

Nonlinear solver: Linear Algebra error. Failed to solve using iteration matrix.
Initial conditions solve failed to converge.
Dependency found among topology equations. Check for missing reference node.

how are additional samples added to the audiostreamer playrec output queue?
If I use the audiostreamer ‘play’ function, I can add additional samples to the output queue by calling ‘play’ when NumberPlayerSamples gets low. But this doesn’t work the same way for the ‘playrec’ function. If I call ‘playrec’ while there are samples in the output queue, it will not add to the output queue, but instead it replaces the output queue with the new samples. Thus, whatever was in the output queue previously was lost.
Is there some reason that it has to be that way? I attached some test code that sends multiple ASIO buffers of pink noise to the output queue and then it starts copying samples from the input to the output. I would expect that the latency from the input to the output would increase if I added more samples up front. Instead I see that it only outputs one buffer of pink noise and then starts copying the samples.
So, bug or intentional? (I vote bug)If I use the audiostreamer ‘play’ function, I can add additional samples to the output queue by calling ‘play’ when NumberPlayerSamples gets low.

Best practices for setting penalty values in objective functions for bayesopt in MATLAB
Hi all,
I’m using bayesop, and trying to design a “safe” objective function: whenever my function encounters out-of-domain inputs,or some kind of errors, I return a large penalty value instead of letting the algorithm fail, although I understand that this algorithm never fails but keeps on running even if it encounters an error.
My typical objective values are in the range of -2 to 2. I’m wondering, does the magnitude of the penalty value influence how bayesopt performs?
For example, would assigning a penalty of 20 have a noticeably different impact compared to a penalty of 1e6? Is there an optimal approach or rule of thumb for choosing penalty values so that invalid points are discouraged, yet the optimization routine remains numerically stable and efficient?
I’d appreciate any insights. Thanks!Hi all,

Use variable values froma code block directly in a Live Script text cell (inline evaluation)

The variable name is not replaced by the value. Has anyone else tried this and had it work successfully? I prefer this to a statement in the code to write a sentence, its just cleaner overall. Any suggestions. tips or known examples that work? Trying out 2025b, does not work on 2023b either. Any help greatly appreciated!

How to incorporate camera calibration in PIVlab
When using PIVlab it seems that the calibration options are rather limited, e.g. as far as I can see one cannot use camera extrinsics to compensate for camera orientation (one can only link pixel size to real world distance). Or should that somehow be taken into account when preprocessing the inout images ? The compensation for camera distortion (intrinsic) has to be done prior to importing the images into PIVlab, it would be great if an integration with the camera calibration app would be added to PIVlab, I’m sure this will save peoples time while a lot of mistakes can be avoided.When using PIVlab it seems that the calibration options are rather limited, e.g. as far as I can see one cannot use camera extrinsics to compensate for camera orientation (one can only link pixel size to real world distance).
