Then we see that data using a type function the type function is used to display the data of contents. Then we open a file using a fopen statement, and then we write these numbers using a fprintf statement, and then we close the file using a fclose statement. Let us consider another example in this example, we take an integer number as we as float numbers, integer numbers are stored in x1 variable, and floating numbers are created by using a rand function (rand function returns a random float number) and these float numbers are stored in y1 variable. And we close the file using fclose statement. We take fscanf in parenthesis we write a fileID1 (text file is indicated by file identifier fileID1) and format specifier, which we defined earlier that is formatSpec and these two arguments are separated by a comma. Then we use the fscanf statement basically, it is used for reading a text file. Then specify the format using ‘formatspec’ we defined as a float.

Let us see the example for reading operation for reading operation, we take a text file textfile1.txt, for a reading operation firstly, we specify the type of access for that we use a fopen statement, we take fopen in parenthesis, we take the text file name which we want to read (filetext1.txt) and the type of access that is reading the file which is specified by ‘r’, and a comma separates these two arguments. Given below are the examples of fscanf Matlab: Example #1 Step 4: Close the file using fclose statement.Step 3: Then, we use a fscanf statement and display the read data.Step 2: Specify the formats specifies and, if needed, then sizeA.Step 1: First, open a file using fopen statement and specify the type of access mode.The steps for reading a text file using a fscanf statement: In the fopen statement, we write a text file name which we want to open and specify a type of access mode. For to open that file using a fopen statement.

= fscanf (_) How to do Matlab fscanf?įor reading data from a text file, we use a fscanf statement. The syntax for fscanf Matlab is as shown below: We need to write data, so the access mode can be ‘w’, ‘w+’, ‘a’, ‘a+’.Hadoop, Data Science, Statistics & others

type of access mode in which the file is to be open.

Before writing to a file, we need to open the text file using fopen() function. Now let’s start writing data to a text file. %c : Display single character(Unicode character) %s : Display string array (Unicode characters) %g : Display the value with no trailing zeros %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.
