fprintf uses the encoding scheme specified in the call to fopen.įprintf(formatSpec,A1.,An) formats data and displays the results on the screen.įor displaying text on screen therefore disp(sprintf()) or fprintf are equal, but if you want to store the results in a string you have to use sprintf and if you want to write it to a text file you have to use fprintf. The MATLAB function fprintf produces formatted output on the screen or in a file. An in column order, and writes the data to a text file. (I used it in the first fprintf call but not in the second.) The ( ) is a newline character. Otherwise it will be to the file you want to write to. Here are examples: > x 1 2 3 4 > x x 1 2 3 4 > disp(x) 1. The fprintf function optionally requires a ‘fileID’ variable as its first argument, with 1 indicating ‘stdout’, that being the Command Window. Str = sprintf(formatSpec,A1.,An) formats the data in arrays A1., An according to formatSpec in column order, and returns the results to string str.įprintf(fileID,formatSpec,A1.,An) applies the formatSpec to all elements of arrays A1. How can I save the information generate in the script below which include strings and table in the following format to a text file Format: M5 1 21 2 22 3 23 4 24 5 25 5points Script: clc clear. Use the fprintf function, which accepts a C printf-style formatting string. What the docs show me is that sprintf is exclusively used for string formatting, which you can use for adding text to a graph, setting up sequential file names etc, whilst fprintf writes to a text file. MATLAB has very readable and accessible documentation complete with working examples for you to try out.
So what happens is that disp(fprintf(.)) first prints the text as per fprintf without a storage variable, but disp sees only the storage variable of fprintf, which is the number of bytes of your string, hence the output.Īs an addition, if you want to display strings, you need STRINGprintf: sprintf: disp(sprintf('Hi %i all of you',2)) This means you can format how the data is printed in such a manner as to make it easy to read. 8f',x) ans 5.20100000 -8323.60000000 0.00030000.
Nbytes = fprintf(_) returns the number of bytes that fprintf writes, using any of the input arguments in the preceding syntaxes. The reason for the specific behaviour mentioned in the question is the call to FILEprintf fprintf with a storage variable:
