Can’t see licenses after payment

PuTI / 2025-10-20

I made an order for licenses and have paid by card. And today is 2-nd day already but I don’t have nor licenses nor even an email about my order.
I just can’t believe that orders are being processed manually in Mathworks.

Matlab Segfaults with OMP Error

PuTI / 2025-10-20

Hi Everyone,
we are a research group, using multiple Matlab versions on some linux systems. After a recent updates, across different Matlab versions, all of them crash whenever matlab decides to multithread a computation. Simple example is a QR decomp via qr(rand(100,100)).

The resulting error is:
OMP: Error #29: Unable to set OMP thread stack size to 525440:
OMP: System error #22: Invalid argument
OMP: Hint Try increasing OMP_STACKSIZE or the shell stack limit.
Segmentation fault (core dumped) ./matlab
and the stack trace is:
OMP: Error #29: Unable to set OMP thread stack size to 525440 bytes:
OMP: System error #22: Invalid argument
OMP: Hint Try increasing OMP_STACKSIZE or the shell stack limit.

One likely culprit is recent updates to glibc that don’t play well with Matlab.
Currently, this really breakes any usage of Matlab for our group. Maybe a recompile of the libiomp5.so might already fix it?
Looks like a Matlab bug. New installation did not fix the problem.Hi Everyone,
we are a research group, using multiple Matlab versions on some linux systems. After a recent updates, across different Matlab versions, all of them crash whenever matlab decides to multithread a computation. Simple example is a QR decomp via qr(rand(100,100)).

How to Run an Indeterminate Number of Simulations with parsim?

PuTI / 2025-10-20

I want to use parsim in Simulink to run a variable (non-fixed) number of simulations, where the number of iterations may depend on the results of each simulation. Normally, parsim requires you to specify all simulation input objects ahead of time, but I need a way to dynamically trigger additional simulations based on logic within the simulation itself.
Is there a way to achieve this kind of adaptive or recursive simulation workflow using parsim?I want to use parsim in Simulink to run a variable (non-fixed) number of simulations, where the number of iterations may depend on the results of each simulation.

license problems “cheat sheet”

PuTI / 2025-10-19

It can be a nuisance to find the meaning of the various license manager error codes, so I have summarized below. Numbered error codes that are not LME errors are listed in the table after that.
In many cases, the error number will be displayed twice to the user, with the first version being the major error number (such as "Error -15") and the second (less obvious) occurance having a more specific subcode (such as "Error -15,570") that acts to narrow down the cause of the error. In the below list, when subcodes are not known for a cause, the known causes are listed under the major error number; but when the subcode is known for the cause, the more specific cases are listed in numeric subcode order. This includes, for example, that the major cause of major error -9 is not listed directly in the error -9 paragraph, and is instead listed immediately afterwards in the error -9,57 paragraph. If you do not have a subcode available, review all of the entries with the same error major error number.

Numbered error codes that are not LME errors are listed in the table after that.
In many cases, the error number will be displayed twice to the user, with the first version being the major error number (such as "Error -15") and the second (less obvious) occurance having a more specific subcode (such as "Error -15,570") that acts to narrow down the cause of the error. In the below list, when subcodes are not known for a cause, the known causes are listed under the major error number; but when the subcode is known for the cause, the more specific cases are listed in numeric subcode order. This includes, for example, that the major cause of major error -9 is not listed directly in the error -9 paragraph, and is instead listed immediately afterwards in the error -9,57 paragraph. If you do not have a subcode available, review all of the entries with the same error major error number.

Numbered error codes that are not LME errors are listed in the table after that.
In many cases, the error number will be displayed twice to the user, with the first version being the major error number (such as "Error -15") and the second (less obvious) occurance having a more specific subcode (such as "Error -15,570") that acts to narrow down the cause of the error. In the below list, when subcodes are not known for a cause, the known causes are listed under the major error number; but when the subcode is known for the cause, the more specific cases are listed in numeric subcode order. This includes, for example, that the major cause of major error -9 is not listed directly in the error -9 paragraph, and is instead listed immediately afterwards in the error -9,57 paragraph. If you do not have a subcode available, review all of the entries with the same error major error number.

How to solve error 1616 for licence activation when old computer crashed and License Center doesn’t show a deactivation tab?

PuTI / 2025-10-19

My old computer crashed. I tried to install Matlab on my new one. Activation generates error 1616.
Mathworks solution to deactivate the old computer does not apply as it already seems to be desctivated. It does not generate a deactivation tab.
When I try to manually activate the license in the License Center, an unspecified error is generated in case the Mac address has been used or it states that `Information needed to identify your computer is missing or invalid.` when the local ip/address (IPv4) is used.
What more can be tried?My old computer crashed. I tried to install Matlab on my new one. Activation generates error 1616.

Parallel computation leaking memory and slowing a loop

PuTI / 2025-10-18

I am doing a parallel computation, specifically a row by row integration of a symbolic matrix (sic I am integrating 4 rows at a time on my quadcore). 2 curious things occur:

*(1)* As the computation progresses, the free RAM steadily gets used up (see graph below). The initial surge in RAM is expected – it is the memory that is "actually" required by the computation. However, I am at a loss to explain why the remaining RAM then steadily continues to be used up. The issue is that eventually, after maybe an hour or so of computation and many rows having been integrated, the RAM is used up. MATLAB then starts to use virtual memory on the HDD, which decreases computation speeds to unacceptable levels (5 fold or so decrease in speed, with further slowing over time). I can circumvent this problem by dividing my matrix into smaller matrices (with fewer rows) that can individually be integrated before HDD switching is required. However, in my estimation this should not be necessary. I have plenty of RAM (16GB) and the actual computation only requires about 2900MB judging by the kink in the graph. Is MATLAB saving output to the RAM? What else could be messing up the memory allocation? The CPU effort never gets above ~65% and is typically around 40%.

<</matlabcentral/answers/uploaded_files/771/memory_allocation.png>>

*(2)* Much more concerning. Before the RAM is used up, a row integration typically takes about 60s per row. However, I just discovered that if I close the worker pool and effectively "reset" my processors (or instead simply restart matlab) and I manually instruct the same exact read/compute/write as is done in the loop, the same computation takes only fractions of a second (see command window dialogue below). I suspect this may be related to (1). This is completely unacceptable, why might this happening?

MATLAB command window output for integration of the first 4 rows:

My source code is attached below (note that symbolic toolbox is required). If you do not have a quadcore processor, you can change _matlabpool open 4_ to _matlabpool open_ [# of processors on your machine]:
