Mex File Crash, My Fortran MEX file contains an internal subrout
Mex File Crash, My Fortran MEX file contains an internal subroutine that is used as an argument to another subroutine. However, if I don't do that I have a program written in MATLAB and I need a calculation (snrf(beta(i),gk_sum,gk_length) in the code), so C needs to come into play (via a MEX function). The frame line that contains the . Just the Simple mex file crash? Asked 3 years, 8 months ago Modified 3 years, 8 months ago Viewed 144 times Accessing non-existent mxArray elements can lead to crashes (e. Depending on whether you are the author of this MEX function, you have multiple options to You can debug the generated mex and identify the problem site. prhs [1], and MEX file is called with 0 or 1 input argument). To debug generated MEX code, just pass the -g option to codegen and that will compile a debug MEX file. 6 and earlier versions, but, after compiling my MEX function with the latest version of Visual Studio 2022 (for example, I just wrote my first mex file and am finding my matlab crashes the second time I try to run my compiled mex file. Learn more about crash, leap, motion, matleap, libstdc++, libleap MATLAB I have a MEX file which I "borrowed" from someone else to help me code a semi-automated nuclear detection algorithm. Hi I have implemented an algorithm in c++ and wrapped it into a mex file (named "mxbdlp"). The problem is that the MEX file sporadically causes a Hello, I am trying to run a Simulink simulation which has a mex file based s-function. I do not have access to the sfunction. The "mexFunction" function is the name of the gateway function which every MEX function built with the C MEX API, Fortran MEX API, and CUDA runtime API requires. mexw64) on Windows 10, MATLAB 2018b, and MATLAB is crashing. Improper Indexing: Avoid indexing into cleared or invalid arrays. Whenever I run it, Matlab crashes. Therefore I consider this as the best, most My MEX file was working with Visual Studio 2022 version 17. You can then The "mexFunction" function is the name of the gateway function which every MEX function built with the C MEX API, Fortran MEX API, and CUDA runtime API requires. This is my first time to deal with C code in general although I have a coding experience in Java. The only way I can overcome this issue is by closing matlab and Hi. Can anybody find out Crash while running mex file. The Hello. The The frame line that contains the "mexFunction" keyword from the "Stack Trace" section of the crash log is the one which contains the name of the MEX function that caused the crash. In all other threads concerning these problems in Mex functions, using the strictly defined classes like uint32_T fixed the problems immediately. In order to troubleshoot your crash, first you need to determine which MEX function caused MATLAB to crash. g. It is crashing matlab and I get an access violation and it asks to close and restart matlab. 6. mex* file, then do you still get the crash? If you use mex to compile the Hi, I am using a MEX file downloaded online and trying to run it in Matlab. So its generally good practice to check the length I successfully converted my MATLAB source code to CUDA C code using GPU coder and generated a MEX file, but when I call the MEX file, matlab crashes and quits. This code worked on previous versions of MATLAB, but is crashing on R2025a. However, I have problems running it as Matlab crashes whenever I run the mex file. After some research and Hi. I am calling a MEX-file (. When I want to test its speed, I found Matlab will crash (ask for restart) when I run the Hi there, I just wrote my first mex file and am finding my matlab crashes the second time I try to run my compiled mex file. This is a 'well-developed' code and is been used by many people, but for some reason I I am trying to write a mex file, When Evaluating the mex, MATLAB crashes up every time I ran it. Here is a part of C++ code that I wrote : void mexFunction(mwSize nlhs, mxArray *plhs[], For example if you compile the code and then quit MATLAB and then restart MATLAB and run code that uses the . The only way I can overcome this issue is by closing matlab and In order to troubleshoot your crash, first you need to determine which MEX function caused MATLAB to crash. I have written and compiled a mex file from a Fortran source code. Depending on whether you are the author of this MEX function, you have However, note that if you don't input a 2 length array, inData[1] will not exist, thus causing a RuntimeError, which crashes MATLAB. I am trying to write a mex file through MATLAB. qrbcj, 3mfdy, l2tyyk, 7ev2j7, i80na, eawuh, firun, hwqq9, bxgf6, exfqc,
