How do I mesh a matlab model

Collision over-simplification in RST
Hello,
I am working with MATLAB to visualize the collision meshes of a robot I’ve designed. When using the show(robot) function, I notice that the collision meshes appear less detailed, I guess, the idea is to optimize execution time and reduce CPU load.
Could you please provide information on the maximum number of triangles allowed per STL file for collision meshes? I aim to achieve a balance between having detailed collision meshes and maintaining computational efficiency.
How it’s supposed to look like :
meshTri = stlread("concept_c-bras5_col.stl");
trisurf(meshTri)
axis equal
How it actually looks like :
rbt = importrobot("concept.urdf");
show(rbt,Collisions="on");
As you can see it’s really ugly. Do you know how to improve the collision meshes make them more accurate ?Hello,

vastly different optimization results from different matlab versions (r2023b,2021b,2020b)
[I just came across the problem and want to put down what I have for now. Will come back to improve the question once I narrow it down. THX]
I was solving a high-dimensional nonlinear optimization problem with self written gradient descent method. Running the exact same code (literally the same file, with no workspace or command window inputs), version 2023b gave me very different results from 2021b. I then compared with 2020b, which produced the same result as 2021b. Comparing the outputs, I found that 2023b calculated the gradient differently.
2020b and 2021b gave the following and converged after 18 iterations.
direction = [4.33783e-06 2.33596e-06 -5.33992e-06 -8.36479e-06 -9.19797e-05 1 ]
2023b gave the following and didn’t converge after 44 iterations.
direction = [4.17191e-06 2.24661e-06 -5.13617e-06 -7.53861e-06 -5.19154e-05 1 ]
The code is very slow, so I can’t let it run forever and find out when it will converge.
As far as I know, my code doesn’t involve any randomness. It does use a lot of matrices and high-order polynomials, as well as conditions.
I went through the release notes from r2021b onwards, and noticed a change to the round function, which I don’t use explicitly but can affect the conditions I suppose?round function change
There’re also some performance improvements on matrix calculations.[I just came across the problem and want to put down what I have for now. Will come back to improve the question once I narrow it down. THX]

Linear Neural Network add another linear layer
I have written a program for training a linear neural network for classification. Both the input and the output are 3 row vectors and I need a each node to have a linear transfer function. I have used the linearlayer type as you can see in the code below;
function trainLNN(P, T)
%P = [1.7300 1.9500 2.3800; 1.4400 5.0000 4.7500; 3.4000 3.2000 3.3000];
%T = [ 0 1 0; 1 0 0; 0 0 1];
net = linearlayer;
net.trainParam.epochs = 1000;
net.trainParam.goal = 0.1;
net.trainParam.lr = 0.001;
net.trainParam.lr = maxlinlr(P,’bias’);
net = train(net,P, T);
What I get is a neural network with just an input and an output layer (see the photo below).
How can I extend that to add a hidden layer between the input and the output layers to have a network like the one in the photo with all nodes having a linear transfer function?

Simulink model doesn’t oscillate
Hi,
I’m trying to model an reaction wheel inverted pendulum and I find this article: https://www.mdpi.com/2079-9292/13/3/514#B1-electronics-13-00514. And now I have to identify the friction coefficient, b_theta. They mesure the natural oscillation of the pendulum by swinging. And then implement this formula in simulink to estimate b_theta by comparing the results:
On the right is my model and on the left is the model present in the article. The probleme is that my simulation doesn’t oscillate, the result is always 0. And i don’t know what the probleme is. I’m using a fixed step of 1e-3 and the solver is on auto (I try multiple solvers but the result is the same).Hi,

Dynamic matrix columns combinations
Hello,
I would like to find all possible combinations of a matrix columns, with each column contribute a value, in each itteration of a loop. The matrix size changes in each itteration. For example:
A = [1 2 3
4 5 6
7 8 9].
should produce:
1 2 3
1 2 6
1 5 3 etc.
but should not produce:
1 4 2 for example.
My problems:
When insert the matrix to combvec function nothing happens. The function accept vectors – and since I do it with different matrix size in each Itteration of a loop I can’t write it manually.
ndgrid also requires vectors – and since I need to choose a combination index in other variable – I’m not clear how this happens.
I don’t have combination function in my Matlab version.
Is there a way to define vectors dynamically in a loop? any idea on to how overcome this? Do I need to write a combination function myself?Hello,

optimization with two-part value range
Dear MATLAB users and MathWorks support team,
I cannot find a solution to represent an optimization problem in MATLAB in which variables in the objective function can take on a two-part value range. The variable in the objective function should correspond to the thermal output of a heat pump in a central heating system. The variable should be able to assume the values 0 (heat pump off) and all values between 100 and 400 (heat pump on with an output between 100 and 400 kW).
x ∈ {0} ∪ [100, 400]
Do you know of a way to implement this condition? I would very much appreciate an answer or the opportunity to discuss this in more detail.Dear MATLAB users and MathWorks support team,

x ∈ {0} ∪ [100, 400]
Do you know of a way to implement this condition? I would very much appreciate an answer or the opportunity to discuss this in more detail. Dear MATLAB users and MathWorks support team,
I cannot find a solution to represent an optimization problem in MATLAB in which variables in the objective function can take on a two-part value range. The variable in the objective function should correspond to the thermal output of a heat pump in a central heating system. The variable should be able to assume the values 0 (heat pump off) and all values between 100 and 400 (heat pump on with an output between 100 and 400 kW).

Running code inspector with a For Loop Iterator
Hello,
I have a model running with a For Iterator (to read an Input Array and write some of its datas to another one shorter array).
The model must go through both Model Advisor and Code Inspector to be embedded in the calculator.
As for the Model Advisor everything is passed and generated code is about 120 lines, however when I try to run the code inspector, it runs for more than 2.5hrs (on the inspection only) and I am forced to kill the Matlab task afterward because it stops running. Here is a screenshot of the model.
Here is what I tried:
include the "add" and the "unitDelaty" inside the referenced model => it creates an algebraic loop
add the triggered block within a referenced model => impossible as it contain an "assignement" block and therefore cannot be referenced.
Simplify the referenced model to reduce load capacity of the model containg.
I can provide the generated C code if necessary
Thank you,Hello,
