MATLAB - Error writing to file using jpeg_write

问题 Recently I added jpeg toolbox to Matlab for Mac OS. for jpeg_read.mexmaci64 I followed this and for jpeg_write.mexmaci64 this. everything was fine but at runtime I got an error like this: Error using jpeg_write Error writing to file. I don't know why Matlab returns this and how Im supposed to fix it. when I compiled jpeg_write.c file to create jpeg_write.mexmaci64, mex operation completed successfully but there was a warning like this. maybe its relevant to the error. Building with 'Xcode

Why does my code fail to buld with Mex but work with cl?

问题 Hey so I'm working to attach a piece of hardware into a setup controlled with MATLAB. I've written a set of functions (tried both C and C++) that utilize this hardware to perform simple tasks. The code compiles just fine using cl. When I try to compile with mex however, it cannot seem to link symbols from my includes (am using the -I flag pointing to directory of my header files). Any thoughts? CL Output: >cl isConnected.c *.lib Microsoft (R) C/C++ Optimizing Compiler Version 19.28.29334 for

Huge fort.# files when running gfortran

由 落爺英雄遲暮 提交于 2020-12-15 03:34:12
问题 I am using gfortran for an application and running the Fortran through a Matlab mex file. I have noticed that in the current directory when I run the Fortran file, on my mac, it creates a fort.9 or fort.16 file, where the 9 or 16 are some arbitrary number. Recently, I have noticed that these fort. files can be GBs big! Generally they are quite small, like a few kBs. I was just wondering what purpose these files have? And second, is there some error I have in my code that is causing them to be

How to fix missing simulink simulation artificats issue when running test in parallel mode?

问题 I have 29 Simulink/Matlab Test. It has a lot of different reference models. Before running a 20 second simulation , it has to load all reference models and create a lot of simulation artifacts in a work folder. A lot of reference model are shared in-between test. When running one test at a time, I have no issue, all simulation artifact are created and used to run the various simulation. Everything Passes. When running it all via parallel processing. I have a issue.Some simulation artifact are

【记录】 编译matconvnet on ubuntu16.04 with cuda 9.0

由 陌路散爱 提交于 2020-11-22 16:35:48
最近需要用到matconvnet 在Ubuntu16.04下。 因为TensorFlow 1.6 支持了CUDA 9.0 所以新机器就直接装了9.0 但是编译matconvnet 时遇到了一些问题 特此记录一下。 1. Error using mex nvcc fatal : Unsupported gpu architecture 'compute_20' Solution: 这个是因为cuda 8 之后不支持compute_20 了，最低也是compute_30了。 所以需要将vl_compilenn.m中的以下代码进行修改 opts.defCudaArch = [... '-gencode=arch=compute_20,code=\"sm_20,compute_20\" '... '-gencode=arch=compute_30,code=\"sm_30,compute_30\"']; 我用的是GTX1080TI, 此处我修改成 opts.defCudaArch = [... '-gencode=arch=compute_30,code=\"sm_30,compute_30\" '... '-gencode=arch=compute_50,code=\"sm_50,compute_50\"']; 同时还需要将 matconvnet/matlab/src/config
