Prior to saving data, you need to initialize a file id. LetвЂ™s run through some examples to get you familiar with the concepts. One easy way to do so is via the fprintf command.

#Matlab fprintf code

ANSI specification X3.159-1989: 'Programming Language C,' ANSI, 1430 Broadway, New York, NY 10018.Saving data to a text file can be a useful way to access results of your Matlab code at a later time.

For example, to make the PC output look like that of UNIX, use

You can resolve this difference in exponents by postprocessing the results of sprintf. Negative Zero Printed with %e, %E, %f, %g, or %G

sprintf prints negative zero and exponents differently on some platforms, as shown in the following tables.

Valid character, it terminates the printing for this %s specifier and is used

One exception is zero, which is a valid character.

For example, pi is formatted by %s below in exponential notation,ДЄnd 65, though representing a valid character, is formatted as fixed-point Printed for this %s specifier using an e conversion as a warning to the

If the first value to print is not a valid character, then just that value is.

Pi terminates the string below and is printed using %f format. Printing for this %s specifier and is used for a later specifier. The first invalid character terminates the

Successive values are printed as long as they are integers and in the.

If %s is used to print part of a nonscalar double argument, the following behavior occurs:.

The function then continues in a similar manner through any additional matrix arguments. The function recycles the format string through the elements of A (columnwise) until all the elements are used up.

The sprintf function is vectorized for nonscalar arguments.

The underlying C data type is a float rather than an unsigned integer.ДЇor example, to print a double value in hexadecimal use the format '%bx'. For example, to print a double-precision value in hexadecimal, use a format like '%bx'.

The underlying C data type is a double rather than an unsigned integer. The following nonstandard subtype specifiers are supported for the conversion characters %o, %u, %x, and %X.To successfully perform this conversion, use the fix, floor, ceil, or round functions to change the value in the double into a value that can be represented as an integer before passing it to sprintf. If you use sprintf 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.The sprintf function behaves like its ANSI C language namesake with these exceptions and extensions. This table lists the escape character sequences you use to specify non-printing characters in a format specification. The following tables describe the nonalphanumeric characters found in format specification strings. Hexadecimal notation (using uppercase letters A- F) Hexadecimal notation (using lowercase letters a- f) The more compact of %e or %f, as defined in. You can control the width and precision of the output by including these options in the format string.ДЄ digit string specifying the minimum number of digits to be printed.ДЄ digit string including a period (.) specifying the number of digits to be printed to the right of the decimal pointД¬onversion characters specify the notation of the output.Д®xponential notation (using a lowercase e as in 3.1415e+00)Д®xponential notation (using an uppercase E as in 3.1415E+00) Left-justifies the converted argument in its field You can control the alignment of the output using any of these optional flags. You specify these elements in the following order: The format string can contain escape characters to represent nonprinting characters such as newline characters and tabs.Д¬onversion specifications begin with the % character and contain these optional and required elements: A conversion specification controls the notation, alignment, significant digits, field width, and other aspects of output format. The format argument is a string containing C language conversion specifications. Sprintf is the same as fprintf except that it returns the data in a MATLAB string variable rather than writing it to a file. errmsg is an empty matrix if no error occurred.

The sprintf function returns an error message string errmsg if an error occurred. Sprintf (MATLAB Functions) MATLAB Function ReferenceДЇormats the data in matrix A (and in any additional matrix arguments) under control of the specified format string and returns it in the MATLAB string variable s.
