By clicking Post Your Answer, you agree to our terms of service, privacy policy and cookie policy. Indexing with Element Positions The most common way is to explicitly specify the indices of the elements. For instance, c = {42, rand (5), "abcd" } c = 13 cell array { [42]} {55 double} { ["abcd"]} To access the contents of a cell, enclose indices in curly braces, such as c {1} to return 42 and c {3} to return "abcd". MATLAB assigns to the variables in column order. Refer to sets of cells by enclosing indices in smooth parentheses, ().
