Note the difference between temp(:,1)=[] and temp{:,1}=[] . An array containing missing values, such as NaN or , is not necessarily empty.. Assigning an empty array is MATLAB speak for deleting the array element. Cell arrays commonly contain either lists of text, combinations of text and numbers, or numeric arrays of different sizes. Compare empty arrays to arrays containing missing values. Create a categorical vector with missing values. That might be more efficient, depending on your application. My aim is to write a code with if condition to check if the cells inside this cell array are empty then put zero for overlapRatio in below code. Instead of using remat, it seems even more convenient and intuitive to start a cell string array like this: C(1:10) = {''} % Array of empty char And the same approach can be used to generate cell array with other data types. Browse other questions tagged matlab cell-array is-empty or ask your own question. Filling Cell Array with Empty value. C(1:10) = {""} % Array of empty string C(1:10) = {[]} % Array of empty double, same as cell(1,10) But be careful with scalers First, check which cells that are empty using the function isempty. ... Be aware that this solution checks a single element within a cell array. My solution checks every element in the cell array individually, and reports whether each cell is empty or not. That might be more efficient, depending on your application. A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. Teams.

It would be great to check if dimension of any cell in a cell called 'Result' is less than 5 say 4x1 make it 5x1 by inseting the empty value at last. This will call a function with each element of a cell array: Some of the cells inside this cell array are empty and have no numbers and have [ ].By clicking on those cells empty page is shown.
