How to export INT8 quantized weight of deep neural network?
I trained neural network using Deep Learning Toolbox, and quantized it.
Below code is what I used to INT8 quantize network model.
% Create a dlquantizer object for quantization
quantObj = dlquantizer(net);
% quantOpts = dlquantizationOptions(target=’host’);
calibrate(quantObj,imdsTrain);
% valResults = validate(quantObj, imdsValidation, quantOpts);
% valResults.Statistics
% Perform quantization
quantObj = quantize(quantObj);
qDetailsQuantized = quantizationDetails(quantObj)
% Save the quantized network
save(‘quantizedNet.mat’, ‘quantObj’);
exportONNXNetwork(quantObj,’quantizedNet.onnx’)
After quantization, I got quantized network quantObj .
However, I cannot access weight and bias which coverted to INT8 format.
When I display quantized networks’ weight and bias using bwloe code,
>> disp(quantObj.Layers(2).Bias(:,:,1))
-6.9011793e-12
It still shows float type value.
Even I tried to export network as ONNX, MATLAB shows below warning,
>> exportONNXNetwork(quantObj,’quantizedNet.onnx’)
Warning: Exported weights are not quantized when exporting quantized networks.

Is it possible to calculate stress in matlab using M,K matrix from ANSYS?
Hello,
Is it possible to calculate stress similar to ANSYS using stiffness, mass matrix, and mesh data exported from ANSYS in MATLAB? I have successfully obtained the final deformation using the HHT-alpha method, which is ANSYS’s transient analysis algorithm with M and K matrix. Although there is a slight difference in values, I believe it’s due to the error in calculating the inverse matrix. Now, I want to calculate the stress using the deformation but I’m having difficulty grasping which method to apply. Is it possible to write code entirely on my own without using the PDE toolbox to achieve stress values similar to ANSYS?
I would greatly appreciate it if you could provide me with any related code, materials, or detail methods.Hello,

Missing faces in .step files for flexibleBodyModelBuilder
Hi,
I’m encountering issues with several geometries that I’m working with in the flexibleBodyModelBuilder tool for Matlab. In the 3D viewer of the tool, some faces aren’t represented, and there’s no explanation, leading to meshing errors and the ROM file not being generated as the body has become hollow. They work fine within Inventor (where they were modeled) and import without issues into other applications such as Ansys Discovery. Are there any workarounds to this issue?
Much obliged,

Implementation of Facenet in Matlab
I’m trying to implement a system that’s identifying faces in real-time – both of known (trained upon) individuals, and unknown persons. In addition, it should put a bounding box around them, with its accuracy score – similar to Facenet. Is there an example of this in Matlab ?
By identifying the known and unknown individuals, we aim at providing the total head-count in a given frame.
I am trying to then later use Matlab coder, to transfer this program to my Nvidia Jetson Platform, so DL models are preferable.I’m trying to implement a system that’s identifying faces in real-time – both of known (trained upon) individuals, and unknown persons.

Export matlab variable to be imported in QGis
Dear all,
I need to export a 1000×1000 matrix containing sound pressure level of a specific region to be later imported at QGis.
I tried to do that using netCDF files, which is ok, however the coordinate system is not the same than in QGis (it is used the WGS84 coordinate system) and when I import the file there it is not in the correct location.
So, my question is, how can I export my variable maintaing the correct coordinate system/or change the coordinate system in matlab to correspond to the same coordinate system in QGIs.
Thank you in advance.Dear all,

I have a problem in using imsegkmeans in a for loop
I’m using several tools in MatLab to segmentate a video I took with a camera. Everything seems to work well, except for the fact that when I ask MatLab to show me the pictures with imsegkmeans they turn out all in different shades of blue and even the binarized image is all blue. However, apparently it’s just a matter of visualization, since I’m using the binarized image to extract height and widht of the object in the video and it works.
Here there is my code:

Now,
I need to make simulink block using MATLAB Function block, which upon giving inputs should generate output by solving multiple functions in one block (like script having many function and run smoothly to give solution)..
