Compiled matlab function does not recognize 'hypercube' function from the 'Image Processing Toolbox Hyperspectral Imaging Library'

21 views (last 30 days)
I have a very simple matlab function that calls the hypercube function (Image Processing Toolbox Hyperspectral Imaging Library) to load hyperspectral data. The codeline is like this: hypercube('path/to/hyperfile.img'). When I run the function in the matlab console, everything works perfectly fine. However, after compiling and executing the function I get the following error: Unrecognized function or variable 'hypercube'
I'm using MATLAB R2021 on a linux server. The command to compile the matlab function is:
/usr/local/MATLAB/R2021b/bin/mcc -o hyper_test -W main:hyper_test -T link:exe -d build/ -v hyper_test.m
I tried something similar to solve the current problem: introducing the hypercube.m when compiling my function
/usr/local/MATLAB/R2021b/bin/mcc -o hyper_test -W main:hyper_test -T link:exe -d build/ -v hyper_test.m a - hypercube.m
but it didn't help. Would be great if someone has an idea how to solve this.

Hi Iris,
'hypercube' function is a part of Image Processing Toolbox Hyperspectral Imaging Library which is a support package. To include support packages, try using the -Z option of mcc. You may try adding
-Z autodetect
Also, I notice in the question above, you have written "-v hyper_test.m a - hypercube.m". I believe you where trying to do "-a" and not "a -".
Hope this resolves the issue you are facing.

Great to hear that the issue you were facing is now resolved. I was able to reproduce the issue in R2021b and would like to share that this issue has been fixed in the latest release of MATLAB.
