MATLAB: Finding integers in an array.

integersnan

Hey Guys,

I have an column matrix that basically consists of NaNs and some integers in between them. Are there any functions in MATLAB that will help me find 1. the first integer value in the array, 2. its location 3. store the value

Thanks, NS

V = [nan;nan;9;nan;6;7;nan;9]  % An example to work with...
idx = find(V==V,1);  % Location.  nan never equals nan...
val = V(idx);  % Value at Location.

MATLAB: 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 vectors

result  = corr(a', b');

MATLAB: How to replace NaN with column mean if less than b NaN in a column

n = nanmean(MA);
nn = isnan(MA);
ii = sum(nn) < 4;
z = MA(:,ii);
z(nn(:,ii)) =  nonzeros(bsxfun(@times,nn(:,ii),n(ii)));
MA(:,ii) = z;

n = nanmean(MA);
nn = isnan(MA);
ii = bsxfun(@and,nn,sum(nn) < 4);
MA(ii) = n(nonzeros(bsxfun(@times,ii,1:numel(n))));

n = nanmean(MA);
nn = isnan(MA);
ii = bsxfun(@and,nn,sum(nn) < 4);
[~,idx] = find(ii);
MA(ii) = n(idx);
