I'm trying to do a plot, just simple plot(timestamps,values), annotating some text boxes, pretty basic stuff and I'm getting this no matter what I do:
LAPACK: Unable to determine CPU type
Error using \
LAPACK loading error:
No valid linear algebra library found for this architecture. lapack.spec is defective or the used architecture is not supported by MATLAB on this machine.
Error in matlab.graphics.controls.internal.PostUpdatePlugin.doCacheLoad
Error in matlab.graphics.controls.internal.PostUpdatePlugin>@()matlab.graphics.controls.internal.PostUpdatePlugin.doCacheLoad(canvasParent)
I'm running an AMD 9950X which isn't exactly a weird CPU, and I'm not sure how to get past this error.
I've replicated the error on R2024a and R2024b so far.
