I've been trying to write a code that can neatly organize the data that is stored in certain variables into a text file. fprintf and sprintf do not create formatted text, they create simple strings of characters. return; fprintf (obj,'format','cmd') writes the string using the format specified by format. The write operation is synchronous and blocks the command line until execution is complete. Otherwise it will be to the file you want to write to. The first one prints the colored string to the terminal. Learn more about for loop, sprintf, fprintf, text file, append return; ...; Command Window text manipulation – Special control characters can be used to format text output in Matlab's Command … Based on your location, we recommend that you select: . colorStrIdxs = [95,96,36,94,92,93,91,1,4]; % OBS! % If no color matched we bold by default % add your own specified colors by adding the color name and its code to the arrays but transpose don't work. There is no mechanism for that, just as there is no mechanism for color or underlining or blinking. end This means no underline, no italic, no bold, etc., because these things only make sense with formatted text. % The fprintf command displays formatted text centered on the icon and can display formatSpec along with the contents of var. % DARKCYAN = '\033[36m'; Related posts: Bold color text in the Command Window – Matlab Command Window text can be formatted *bold* since R2011b. coloredStr = strjoin({'\033[1m',str,END,'\n'},''); Unable to complete the action because of changes made to the page. % BLUE = '\033[94m'; Note: Matlab does not currently support both bold and underline, only one of them can be used in a single cprintf command. The suggest methods have the benefit, that they can show 'true', 'True', 'TRUE', 'On', 'Yes', 'Enabled' or what ever. Save my name, email, and website in this browser for the next time I comment. fprintf (fid, '\\begin {table}') You also need to use %% to represent any % characters that must appear literally, such as If you happen to be outputting to a terminal emulator (e.g., if you are running matlab -nodesktop) then you may be able to take advantage of the ANSI sequences for text attributes: http://en.wikipedia.org/wiki/ANSI_escape_code#graphics, https://www.mathworks.com/matlabcentral/fileexchange/24093-cprintf-display-formatted-colored-text-in-the-command-window. One easy work-around would be to simply create a new line of characters to print under the title string: If is based on the same base functions as the C version. The default format is %s\n. END = '\033[0m'; I am writing a lot of date to a text file one line at a time (1.7 million rows, 4 columns) that is comprised of different data types. The above are for output to the command window. % If no color specified we bold by default Hi all, I'm very very unfamiliar with MATLAB. colorStrIdxs = [95,96,36,94,92,93,91,1,4]; % CYAN = '\033[96m'; % DARKCYAN = '\033[36m'; You can download them in a zip file here: colorstrings, function printc(str,color) You can download them in a zip file here: colorstrings function printc (str,color) % Prints a colored version of the string to the terminal in Matlab. % GREEN = '\033[92m'; For example, let’s write the word “Text” into a file named “textFileName.txt”: fprintf(coloredStr); Luckily there is fprintf and the idea that things will work just as in the ordinary terminal when you want to color strings or make them bold. fprintf(obj,'format','cmd') writes the string using the format specified by format. Very easy to use! https://www.mathworks.com/matlabcentral/answers/22744-how-to-bold-italics-sentence-using-fprintf-in-matlab#answer_29925, https://www.mathworks.com/matlabcentral/answers/22744-how-to-bold-italics-sentence-using-fprintf-in-matlab#comment_700313, https://www.mathworks.com/matlabcentral/answers/22744-how-to-bold-italics-sentence-using-fprintf-in-matlab#answer_373068, https://www.mathworks.com/matlabcentral/answers/22744-how-to-bold-italics-sentence-using-fprintf-in-matlab#comment_871999, https://www.mathworks.com/matlabcentral/answers/22744-how-to-bold-italics-sentence-using-fprintf-in-matlab#comment_994762. fprintf (obj,'cmd') writes the string cmd to the instrument connected to obj.

Copyright © 2021 The NonConditional Beast - All Rights Reserved, % Prints a colored version of the string to the terminal in Matlab. The write operation is synchronous and blocks the command line until execution is complete. return; % add your own specified colors by adding the color name and its code to the arrays Is it possible to provide a text in bold and underlined using the command fprintf? colorNames = {'PURPLE','CYAN','DARKCYAN','BLUE','GREEN','YELLOW','RED','BOLD','UNDERLINE'}; % below. Thanks for the abbreviation hint! % Prints a colored version of the string to the terminal in Matlab. I wrote two functions for doing this. You can print bold only (not italics) using fprinf as shown below. for idx = 1:numel(colorNames) Other MathWorks country sites are not optimized for visits from your location. coloredStr = strjoin({'\033[1m',str,END},''); When i open the text file the data are still on a row. coloredStr = strjoin({'\033[1m',str,END},''); end % PURPLE = '\033[95m'; The following statement demonstrates the use of { \boldmath}: text ('position', [0.5 0.5],'Interpreter','latex','String',' {\boldmath$\alpha$}') fprintf(coloredStr); My example: fprintf(fid_log,'\n\t -> Nombre de ligne d''erreur contenant un nbre de champs = au nbre attendu : %d', size_temp_mer_egal125); Required fields are marked *. end, function coloredStr = colorstr(str,color) Always great that these minor syntactical hurdles that relatively new Matlab users confront can easily be found and answered on the MATLAB Answers forum. The write operation is synchronous and blocks the command line until execution is complete. fprintf () is for transferring characters, and characters do not have inherent attributes or font properties. Accelerating the pace of engineering and science. To do this, go through the following 3 steps: Open a file using fopen. "tried adding %s to the fprintf command" - Obviously there is a mistake in this trial, so prefer to post the code instead of describing it by words. % BOLD = '\033[1m'; % OBS! colorNames = {'PURPLE','CYAN','DARKCYAN','BLUE','GREEN','YELLOW','RED','BOLD','UNDERLINE'}; fprintf(obj,'format','cmd') writes the string using the format specified by format. % RED = '\033[91m'; After the array is stored, I use fprintf to write the array into an data file, and then later on the string within the array is replaced within a new string and the cycle repeats. Otherwise, it creates a bold object that specifies to use regular weight text. fprintf(obj,'cmd') writes the string cmd to the instrument connected to obj. It is easy to, % add your own specified colors by adding the color name and its code to the arrays, % If no color specified we bold by default, % Returns a colored version of the string to the terminal in Matlab.
