Linear index
Nettet2. apr. 2011 · Indexing into a matrix with a single subscript in this way is often called linear indexing. Here are the elements of the matrix A along with their linear indices: The linear index of each element is shown in the upper left. From the diagram you can see that A(14) is the same as A(2,4). NettetThe element at row 3, column 2 of matrix A (value = 5) can also be identified as element 6 in the actual storage sequence.To access this element, you have a choice of using the standard A(3,2) syntax, or you can use A(6), which is referred to as linear indexing.. If you supply more subscripts, MATLAB calculates an index into the storage column based …

Nettet‘linear’: Ignore the index and treat the values as equally spaced. This is the only method supported on MultiIndexes. ‘time’: Works on daily and higher resolution data to interpolate given length of interval. ‘index’, ‘values’: use the actual numerical values of the index. ‘pad’: Fill in NaNs using existing values.
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. horst hohmann fuldaNettetObjective: Systemic immune-inflammation index (SII), a novel inflammatory indicator based on platelets, neutrophils and lymphocytes, has been shown to be associated with prognostic value in several solid tumors.

To get the subscript indices, use the find function with two output arguments.
