The fprintf function allows you to "write" information to the screen for the user to view. This very important when user interaction is involved. The 'f' in printf stands for formatted.

Help Center Help Center. To convert data to text and control its format, you can use formatting operators with common conversion functions, such as num2str and sprintf. These operators control notation, alignment, significant digits, and so on. They are similar to those used by the printf function in the C programming language. Typical uses for formatted text include text for display and output files. You can combine operators with ordinary text and special characters in a format specifier. Functions that support formatting operators are compose , num2str , sprintf , fprintf , and the error handling functions assert , error , warning , and MException. A formatting operator can have six fields, as shown in the figure.

In order to do so, we might run the following:. During the write process, fprintf will read down each column instead of across each row. To properly display the matrix, you will need to transpose matrix A.
