MATLAB: Error using nanstd function

Question

B=nanstd(X,0,'all');

when using the above statement in Matlab R2019a there are no problems, however when using it on another computer with R2017a, i get the error:

Error using size

Dimension argument must be a positive integer scalar within indexing range.

Error in var (line 109)

n = size(x,dim);

Error in nanvar (line 32)

y = var(varargin{:},'omitnan');

Error in nanstd (line 28)

y = sqrt(nanvar(varargin{:}));

Answer 1

If you're computing the std over all elements of X, this works in any release.

B = std(X(~isnan(X)));
