Log(A) calculates the natural logarithm of each... The two main ways to process numeric data in a cell array are: Combine the contents of those cells into a single numeric array, and then process that array. Process the individual cells separately. To combine numeric cells, use the cell2mat function. The arrays in each cell must have compatible sizes for concatenation. Alternative Approach. You can adopt a new approach that translates the input of cell array of cell arrays of strings to cell array of strings, thus reducing one level "cell hierarchy".Then, it performs strcmp and thus avoids cellfun or arrayfun, which might make it faster than earlier listed approaches.Please note that this approach would make …

Open in MATLAB Online. I have an n-value structure array with multiple fields, and want to extract a specific field (all values thereof are (1x4) single arrays) into a nx4 array. Theme. Copy. MyMatrix = [MyStruct (:).FieldC]; concatenates the values of the field, giving me a 1x (n*4) array. There's probably a way to reshape that, but I would ...Cell arrays follow the same basic rules for expansion, concatenation, and deletion as other types of MATLAB® arrays. However, you can index into a cell array in two ways: with curly braces {} to access cell contents or with parentheses to refer to the cells themselves. Keep this distinction in mind when you add, delete, or combine cells in a cell array.The corresponding character vector would be fp31 {1} Sign in to comment.

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. C(1:10) = {""} % Array of empty string C(1:10) = {[]} % Array of empty double, same as cell(1,10) But be careful with scalers

There is no need for the loops, just transpose the cell array and then use {:} to convert it to a comma separated list. fprintf repeatedly applies the format string to all of the input arguments, so it does the looping for you! Theme. Copy. D = C'; fprintf ('%s %s %d %d %d %3.2f\n',D {:}) and it prints this text in the command window: Theme. Copy.
