The K>> prompt in the The format argument is a string containing C language conversion specifications. fprintf('I am a very long piece of text that can definitely not fit on one line, \nhowever as I want my code to be readable to anyone that may access it.\nI need a way to split this across various lines\nwithin the live script.\n') The output of this would be fine: fprintf(ID, '%g is the value', x) ValueOfX is the value Same as sprintf except Matlab outputs the to the ID instead of the console It is clear that by displaying to an ID of the user’s choice while also permitting formatting, the most robust of these methods is fprintf. which builds multiple columns and then transposes into multiple rows, [r(1) a(1); r(2) a(2)] transposed to [r(1) r(2); a(1) a(2)] the in-memory order of which would be [r(1) a(1) r(2) a(2)] so everything gets parcelled out to the correct format descriptor. You have to select the right answer to a question. fprintf (fileID,formatSpec,A1,,An) applies the formatSpec to all elements of arrays A1,An in column order, and writes the data to a text file. This is done by inserting \n before the character that will start the new line. (I used it in the first fprintf call but not in the second.) Instead, it create a character looks like small circle with black background, shown in figure below.
