Description. 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. fprintf uses the encoding scheme specified in the call to fopen. example.
The fprintf Function. from Serhat Beyenir, 1.4. The fprintf function writes formatted data to the computer monitor or a file. This command can be used to save the results of a calculation to a file. To do this, First we create or open an output file with fopen; Second we issue the fprintf command; Then we close the output file with fclose.
Output with fprintf requires the function, itself, with the arguments of the output ID, con-version character and value. Example 1, below, illustrates the ease of outputting variables M-File Console ID = 1; x = 1234.5678; fprintf(ID,'%f',x); 1234.567800 Example 1. Ease of Output BASIC FORMATTING Sometimes the ability to output a single value is ...
(B.1) Using fprintf( ) with arrays: If you only specify one formatting command, all elements of an array will be printed on a single row (even multidimensional arrays). For multidimensional arrays, elements will be printed off one column at a time. M-file: x = (1 : 0.25 : 2) y = [1,4,7 ; 9,8,6]; fprintf('%7.2f' , x) fprintf('\n')
8 mar 2019 · For example, with the second approach it would be fprintf(['data points: ' strjoin([repmat({'%.8g'},1,numel(a)+numel(b)+numel(c))])],a,b,c). With the third: fprintf(['data points: ' sprintf('%.8g ',a,b,c)])
The fprintf function is vectorized for nonscalar arguments. The function recycles the format string through the elements of A (columnwise) until all the elements are used up. The function then continues in a similar manner through any additional matrix arguments.
