What Does Fprintf Do In Matlab

The sprintf function is similar to fprintf but fprintf prints to a file or to the command window.

What does fprintf do in matlab. Format of the output fields specified using formatting operators. If formatspec includes literal text representing escape characters such as n then fprintf translates the escape characters. If you use fprintf to convert a matlab double into an integer and the double contains a value that cannot be represented as an integer for example it contains a fraction matlab ignores the specified conversion and outputs the value in exponential format. Formatspec also can include ordinary text and special characters.

Do not use this option except for quick debugging. Formatspec can be a character vector in single quotes or starting in r2016b a string scalar. Note while this fprintf function is identical in name to its corresponding matlab function it provides only the functionality described on this page. For the f e and e operators the precision indicates how many digits to display to the right of the decimal point.

The reading functions do not support a precision field. How to print the string value using fprintf. The fprintf function behaves like its ansi c language namesake with these exceptions and extensions. For example in the operator 7 3f the precision is 3 for the g operator the precision indicates the number of significant digits to display.

The precision field in a formatting operator is a nonnegative integer that immediately follows a period. Fprintf is the preferred method when to print information. The fprintf command displays formatted text centered on the icon and can display formatspec along with the contents of var. For example a function that compute pi should never use fprintf.

Format specifiers for the reading functions sscanf and fscanf differ from the formats for the writing functions sprintf and fprintf. If you use fprintf to convert a matlab double into an integer and the double contains a value that cannot be represented as an integer for example it contains a fraction matlab ignores the specified conversion and outputs the value in.
