In both machines, mex -setup identified gcc as compiler, though I don't know why I had to manually install the extra library on the second machine.

But in both cases the errors disappeared once the compilation was successfully done.

That's a nice observation. If you turn the triangle to the third direction (i.e. Exp.SampleFrame = [0 pi/2 pi/2] ), you will see that the effect is reversed: Hstrain_x has no effect and only Hstrain_y counts. I don't have a complete explanation in mind, but it might help to note that: In Exp.SampleF...

And the solution this time was:

Code: Select all

sudo apt install g++-multilib

One issue I came across and how it can be solved: The esfit function in the 6.0.0 version apparently makes a call to a new function called esfit_algdefaults , which caused an error: Unrecognized function or variable 'esfit_algdefaults'. This is located in the easyspin/private folder, which Easyspin ...

Overall, pairwise dipolar couplings can be calculated explicitly. This must be done for all spin pairs, just like exchange interactions. In the case of the dipolar couplings between anisotropic spins, each spin's gFrame, along with each interspin vector needs to be explicitly provided. Then each 3x3...

You may be looking at GNU Octave, but I doubt all ES functions can be executed.

esfit(spc,@garlic,{Sys0,Exp},{Vary});

Just a suggestion: try introducing an asymmetry to your system, e.g. by varying one of the two g values.

What does that give?
