Before writing to a file, we need to open the text file using fopen() function. The solution is here for windows machine. Now let’s start writing data to a text file. %c : Display single character(Unicode character) %s : Display string array (Unicode characters) Diary (or log) file of keystrokes and the resulting text output. Rectangular, delimited ASCII data file from an array. For this, MATLAB provides several data export options. MATLAB allows you to use your data in another application that reads ASCII files. abc.txt, or add argument s into input () function call Theme a input nEnter with a matrix. Data export (or output) in MATLAB means to write into files. %g : Display the value with no trailing zeros Type name of the file with apostrophes e.g. %e : Display the value in exponential format The different format specifiers used with fprintf() function are: %d or %i: Display the value as an integer A formatting operator starts with a percent sign% and ends with a conversion sign. The formatSpec is used to format ordinary text and special characters. The format of the output is specified by formatting operators. Declare variable to read file (optional). Create a text file by using ‘dlmwrite’ syntax ( dlmwrite (filename, data ). Steps to read excel file in Matlab: Clear workspace.
