I am currently running the Ncorr software with matlab and need to pull the strain data from it.

The below is the data in structure form and I can't figure out how to get the values out of the "strains" section. I tried simply doing [struct.strains] but the I get the error "The class struct has no Constant property or Static method named 'strains'". I don't care how the values are presented, I just need the numbers to put in a research notebook.

>> handles_ncorr.data_dic

ans =

struct with fields:

displacements: [1×152 struct]

dispinfo: [1×1 struct]

strains: [1×152 struct]

straininfo: [1×1 struct]

Thanks for the help in advance and let me know if further information is needed!
