For any input cell whose text does not contain 'bla', "strfind" returns an empty cell. In previous versions of MATLAB (before R2016b), you can use the "strfind" function. For example, D = find (Y) remits a vector containing the linear indices of each nonzero element in array Y. Choose a web site to get translated content where available and see local events and This is checking for string in elements and I want to check for elements in string. Choose a web site to get translated content where available and see local events and It just escapes me as to how to locate the matching character vector with native functions.

Unable to complete the action because of changes made to the page. Use "isempty" and "cellfun" with the "find" function to find the empty cells. Below is a picture of a subset of the cell array. The relational expression can be used in conjunction with find to find the indices of elements that meet the given condition. index = strfind(cellArray,refString); index = find(~cellfun(@isempty,index)); Result: index = 3 5 This method works great if the idea is to find a substring, i.e. If Y is a vector, then find returns a vector with the same orientation as Y. I already tried approaches like strcmp or strfind, but I am still stuck. an error message.
