MATLAB: Isolate data elements out of a column on NaNs arrayindexingMATLABnan I have a large column of mostly "NaN" but it does periodically include actual data. Is there a way I can extract those data to form another vector? Best Answer a=[0 nan 1 nan];b=a(~isnan(a)) Related SolutionsMATLAB: Correlation between two row matrices Like that, each value of "a" is correlated to each value of "b", but applying the formula of the correlation, the correlation of two single numbers is NaN. To compute the correlation correctly, traspose the input vectorsresult = corr(a', b'); MATLAB: Sorting without moving NaNs Use a variant of the same trick:A=[6 20; 10 10; 3 NaN; 20 66; 4 NaN; 7 12]B = flipud(sortrows(A,[2 1])) ; % descending sortrows based on 2nd columnA(~isnan(A(:,2)),:) = B(~isnan(B(:,2)),:) Related QuestionIgnoring NaNs for polyfitSame matrix but not equal problemFinding out number of columns with no NaNsGet rid of NaNsConstructing an if statement when a column contains only one data point and the rest are NaNs
