NettetAccess Element of 3-D Array. Convert a subscript index of a 3-D array to a single linear index. Create an array, and find the linear index corresponding to the element in the (2,1,2) position. A = rand (3,4,2); linearInd = sub2ind (size (A),2,1,2) linearInd = 14. Check that both index versions refer to the same element. NettetLinear regression analysis revealed that ΔRRi supine-M-RSA was independently related to DL CO ( r =-0.77, r2 =0.43, P <0.05). Conclusion: Responses of HRV indices were more prominent during M-RSA in moderate to severe COPD. Moreover, greater lung function impairment was related to poorer heart rate dynamics.
