vcredist_x86.exe cannot be found
I’m receiving the following error that prevents MATLAB R2010a (x64) from starting:
=========
*Windows cannot find ‘C:Program FilesMATLABR2010abinwin32vcredist_x86.exe’. Make sure you typed the name correctly, and then try again.*
=========
I have noticed that it happens when Windows Update detects that there are updates available for Windows. I doesn’t install them, just detects that they exists.
The running instances of matlab continue running without any error but I cannot start further instances. Even if I quit from all the running Matlab instances and try to start a new instance the error persist. The only way around this I found is to restart the computer. However, I am fed up of that. WTF is going on here?

How to use for loop for iterations.
for i=1:3
a=rand(3,1);
b=5.*(a.^2);
c=[a b]
end
At the end i get a value of c that is of the order of 3×2, that is the final value that comes after3rd iteration. So value of c gets changed in each iteration.
How I can get all value of c of the loop.
In other words i want to get c of the order 9×2 (3 iterations and three values for each iteration).for i=1:3
a=rand(3,1);
b=5.*(a.^2);
c=[a b]

LSTM model predicts wrong values?
Hello, Im trying machine learning with LSTM and unsupervised learning.
Here is trained LSTM network, and I checked this model works.
numHiddenUnits = 100;
Layers = [ …
sequenceInputLayer(1, Normalization="zscore")
lstmLayer(numHiddenUnits,’OutputMode’,’sequence’)
swishLayer
fullyConnectedLayer(1)
myRegressionLayer(‘mae’)
];
options = trainingOptions(‘adam’, …
‘MaxEpochs’,40,…
‘MiniBatchSize’,32,…
‘GradientThreshold’,1,…
‘InitialLearnRate’,1e-2, …
‘Verbose’,false, …
‘Plots’, ‘none’);
%XTrain is (n*t sequence data)
%YTrain is (n*t sequence data)
[net, ~] = trainNetwork(XTrain, YTrain, Layers, options);
However, if the model predicts values with inputs in other environment,
%XTrain2 is (n*t sequence data in different environment from XTrain and YTrain environment for unsupervised learning)
dist = predict(net, XTrain2);
only head of sequence of output is lower than others as shown below.
Here is input data, and it doesn’t seem that there are differents of value between head of sequence and other parts.
In comparison with true data, this head of sequence of output is wrong value, and other sequence parts are comparatively correct values.

how to draw a peak line
Hi, i’ve data and i want to draw a line that corresponds to the peaks (where there is a zero the previous value >0 must be pasted) (See black line painted)
Is there a function or graph type that does this to me?Hi, i’ve data and i want to draw a line that corresponds to the peaks (where there is a zero the previous value >0 must be pasted) (See black line painted)

MATLAB Vehicle Network Toolbox cannot send CAN messages on physical channels with Vector’s hardware VN1610.
When using the vehicle network toolbox(Matlab 2024a update 6) with the vector’s hardware VN1610, if choosing to use the real physical channel instead of the virtual channel, I’m not able to turn off the canChannel.SilentMode even if the canChannel.InitializationAccess is 1, which caused the channel only able to receive messages but cannot send out any messages. I tried to turn the SilentMode off with commands below:

It’s wierd that the channel has opened successfully but SilentMode is set to 1 defaultly, and the initial access is true but cannot change the SilentMode without giving any error or indication. When I dig the issue further, I found that this issue only happens on the hardware VN1610 with the latest Vector driver(version 24.20.10).
After rolling-back the driver to a previous version, the issue just disappeared:
Vehicle Network Toolbox has detected a supported Vector device. To connect to this device:
1. Download and install the latest device driver from the Vector website.

Choose role of NaN when summing two matrices
Dear all
Some time ago, I posted this question: Choosing the role of NaN elements in the sum environment of matrices. That worked great when doing the mean value, but now imagine that I just want to sum the two matrices, given by:
aa=[1 2; 3 NaN];
bb=[NaN 1; 2 NaN];
so that I obtain:
cc=[1 3; 5 NaN];
If I do something like:
cc=sum(cat(3,aa,bb),3,’omitnan’)
that gives:
cc=[1 3; 5 0];
Which way would be the best in this case?Dear all
