Plotting vehicleCostmap in App designer
Hello all,
I am working on parking area designer using matlab.
i want to show my vehicle cost map on app designer plot window. but i am getting error "Error using plot Data must be numeric, datetime, duration or an array convertible to double."
could any one guide me how to solve this problem?
Any lead will be really supportive me for me!!

Get/set geoglobe view angle
With non-GeographicAxes, camva() can be used to get/set camera viewing angle. This doesn’t seem possible for uifigure+geoglobe figures. Is there a way to at least get the viewing angle? The purpose is to simulate what a camera with a particular lens would see.With non-GeographicAxes, camva() can be used to get/set camera viewing angle.

ElevationResolution value: NaN | IWR1843BOOST
I’m using the TI IWR1843BOOST with SDK version 3.06. The test involves flashing the bin and loading the cfg file generated from mmWave demo visualizer 3.6.0. Upon running mmWaveRadar(), I get output including sensor properties. However, the ElevationResolution is NaN, even though the 3D point cloud data can be read correctly from Demo visualizer but not in MATLAB. Are there any differences in the cfg extraction process in MATLAB that might cause this discrepancy?I’m using the TI IWR1843BOOST with SDK version 3.06.

How to create the designed simulink block with the desired Inline function
hello.
I have a question about how to create an inline function in simulink coder.
I understand that you can select Inline in the Code Generation Tab of ‘Block Parameters’ in Simulink.
However, this is not the way I want to generate code.
Does Mathoworks support the method of generating code in the form of an inline void function as shown below?
If so, could you tell me how?
thank you

How to measure impedance in low voltage circuits
Hi there,
I need some help at the following model. I woud like to measure the impedance of the circuit. I tried by measuring V and I and then analyze their quotient by using ‘Linear Analysisi Points’ however, I haven’t found such option when selecting the lines (i.e. Input or Voltage) and clicking right mouse’s button.
Have I missed sth? I already installed Linear System Analyzer app, I’m not sure wether it help, though. If you have any other preposition please let me know.Hi there,

Training in programming FPGAs in Matlab/Simulink using examples: from simple to complex
Hi!
I’m a beginner and want to learn FPGA programming. I was very attracted by the possibility of interconnected work of Matlab/Simulink with codes for FPGAs, as well as the possibility of testing algorithms developed for FPGAs in Matlab/Simulink.
I have a certain idea in the spirit of: “We place the element/elements in Simulink, convert it into one of the languages VHDL/Verilog/etc., sew it into the FPGA or into the FPGA simulation program, debug and complete the project” or vice versa “We write the program on VHDL/Verilog, copy the code into Simulink, assemble the circuit, simulate".
I would like to try to do something on my own, but unfortunately there are several blind spots in my idea, namely: the sequence of the conversion process in Simulink; it is unclear how both a digital circuit and PID control can be embedded in an FPGA; is it possible to convert any block from Simulink into the FPGA code.
As the first two projects I would like to implement the following:
1. Simple asynchronous RS-trigger.
2. A simple PID-controller to control the output of an aperiodic link with a transfer function .
I’m asking for some advice on how to do this. I’ll practice. I would be very grateful and grateful for your help in overcoming this milestone.Hi!

initialize persistent variables using Matlab coder
My Matlab code utilizes a few persistent variables and currently uses "isempty" for one of the variables to ensure all are intialized before use. The resulting Matlab coder initialization function sets a bool "var_isempty". This seems rather clunky. To me it seems that the appropriate coder output should instead initialize the values in the static variable definition within the function.
Is there a codegen option to generate the code in this manner? Or another way?

Why does my fit to a PDF generated using a histogram not add up to 1 or give me correct expected value?
Hello,
I generate a pdf from a histogram which describes the distribution of values about an average. For example say I have values {x1,x2,….xn}, my PDF is to see how x’={x1,x2,….xn}/mean({x1,x2,….xn}) is distributed.
The PDF of x’ (blue curve) i generated is shown below where I fit a yellow quadratic function to whatever is below the mean <1 and with an exponential fit to whatever is >1.If I sum the blue curve:
(sum(prob))
it is 1 which makes sense since probabilities should add up to 1. In addition, if I do:
sum(x’.*prob)
for the distribution, I get 1 which makes sense because my expected value should be 1. However, If I try to do the same with my curve fits, using trapezoidal integration, I do not get 1! I don’t understand what is missing.. am I not normalizing a quantity?
The full code snippet I used to generate the above figure is attached below. I have also attached the data to this post if you might be interested in taking a look. My expected value from the discrete distribution given by the variable ‘discrete’ is nearly 1. but the ‘continuous’ variable when computed is like 0.18 which is unexpected.

Figure in shrunk on screen when dimensions are set for publishing
I want to create a figure of 5 x 5 cm to insert as a panel on a larger figure for academic publishing. I would like to set the fontsize in matlab so that it is consistent across panels (ie. 8). I could for example export the figure with exportgraphics and rescale the figure in an image editor but then, the fontsize ends up being scaled also, which I do not want.
My problem is that if I set the figure dimension to 5×5, its appearance on the screen (4K resolution) becomes very small (spanning around 100 x 100 pixels on screen). I would like to be able to scale the figure displayed on the screen so that the 5 x 5 cm figure spans say 1000 x 1000 pixels (similar as in a pdf which you would open and zoom in).I want to create a figure of 5 x 5 cm to insert as a panel on a larger figure for academic publishing.

Creating a 2D Lookup Table for PMSM in EV Applications Using Simulink
Hello MATLAB Simulink Community,
I am currently working on developing a 2D Lookup Table for a Permanent Magnet Synchronous Motor (PMSM) to optimize its operation in an electric vehicle (EV). My objective is to collect data on motor torque, Vde (d-axis voltage), and Vqe (q-axis voltage) under conditions of limited back-EMF WHILE changing Beta-angle and stator Current. This data collection is critical for optimizing motor control strategies(MTPA, Field-Weakening control)
Here are the specific aspects I need help with:
Speed Control Setup: I need to implement a control system in Simulink that allows the PMSM to operate at set speeds to run with limited back-EMF. Which blocks or models would be best for controlling speed of a PMSM regardless of current of PMSM in Simulink?
Data Collection for LUT: As the motor runs, I need to systematically record the torque, Vde, and Vqe. What are the best practices for setting up data logging in Simulink for these variables, especially considering the impacts of limited back-EMF?
Lookup Table Generation: Any advice on how to automate the generation of a 2D LUT based on the collected data within Simulink would be greatly appreciated.
Could you please provide guidance or suggest resources, blocks, or toolkits in Simulink that could be useful for these purposes? Additionally, if there are example models or tutorials related to advanced PMSM control, including speed control and regenerative braking, those would be very helpful.

4 walls vs 1 wall – House regulation on heating
Hi MathWorks team,
While studyin a House Heating system, I failed to understand why would the model of the house only have one wall insted of 4 walls and a floor ? (House Heating System)
I’m trying to model my own model on this theme, that is a room heating system for starters.
