function tf = hasMissingVal(v) %HASMISSINGVAL Identify rows of an array that have missing values. % TF = hasMissingVal(X) returns a logical vector with one value per row % of X, indicating whether any value in that row is missing. Missing % value indicators are NaN for floating point types, "<undefined>" for % categorical types, empty '' for cell arrays of character vectors, % <missing> for string arrays, NaT for datetimes, NaN for durations, or % entirely blank for character arrays. % Copyright 2013-2016 The MathWorks, Inc. v = v(:,:); if isfloat(v) tf = any(isnan(v),2); elseif iscategorical(v) tf = any(isundefined(v),2); elseif iscellstr(v) tf = any(cellfun('isempty',v),2); elseif ischar(v) tf = all(v == ' ',2); elseif isdatetime(v) tf = any(isnat(v),2); elseif isduration(v) tf = any(isnan(v),2); elseif isa(v, 'string') tf = any(ismissing(v), 2); else % including integers tf = false(size(v,1),1); end
