Now let’s see the formatting operator in Matlab as follows.įormatting Operator for sprintf in Matlabįormatting operator uses % sign to start and with the conversion character compulsory. The format of formatSpec is a single quote or string. Sometimes formatSpec uses the literal text at that time sprintf translation of all characters. Here we use the formatSpec formatting operator and it includes text and special characters. 1 formatSpec:įormatting of output we specified by using different operators. Sprintf uses different input arguments as follows. In Matlab, we have an option to format the text under control by using the sprintf() function as well we can use the formatting operator with the different conversion characters. We can format the text as per our requirement by using the different input arguments and different data types. Now let’s see how to use sprintf() in Matlab as follows.įormatting text is the main part of the sprintf() function. In the third line, we try to print the literal text such as \n and \t. In the Second syntax, we use error messages when our transaction is unsuccessful otherwise it shows empty error messages. Notice here if formatSpec is a string then it returns the result into a string else the return result is a character vector. Here we also used Array1, Array2 for column order and it is formatted by using the sprint(). In the first syntax, we specify the data into array formats using the formatSpec formatting operator and that helps us to return the result into a string from the text. ANSI specification X3.159-1989: " Programming Language C," ANSI, 1430 Broadway, New York, NY 10018.There are multiple syntaxes available for sprintf() in Matlab as shown in the above syntax. Ritchie, The C Programming Language, Second Edition, Prentice-Hall, Inc., 1988. Line termination character on all platforms Left-justifies the converted argument in its field.Ī digit string specifying the minimum number of digits to be printed.Ī digit string including a period (.) specifying the number of digits to be printed to the right of the decimal point. Other characters can be inserted into the conversion specifier between the % and the conversion character. Hexadecimal notation (using uppercase letters A- F) Hexadecimal notation (using lowercase letters a- f) The more compact of %e or %f, as defined in. Tables The following tables describe the nonalphanumeric characters found in format specification strings.Ĭonversion characters specify the notation of the output.Įxponential notation (using a lowercase e as in 3.1415e+00)Įxponential notation (using an uppercase E as in 3.1415E+00) Reinitializing, through any additional matrix arguments. It is then cycled in a similar manner, without Theįormat string is cycled through the elements of A (columnwise) until all theĮlements are used up. sprintf is vectorized for the case when input matrix A is nonscalar. The underlying C data type is a double rather than an unsigned integer.įor example, to print a double-precision value in hexadecimal, use a formatĢ. The underlying C data type is a float rather than an unsigned integer. The following nonstandard subtype specifiers are supported for conversion Remarks The sprintf function behaves like its ANSI C language sprintf() namesake with certain exceptions and extensions. Returns an error message string errmsg if an error occurred or an empty matrix if an error did not occur. It can contain ordinary alphanumeric characters along with escape characters, conversion specifiers, and other characters, organized as shown below:įor more information see "Tables" and "References." = sprintf( format,A.) The format string specifies notation, alignment, significant digits, field width, and other aspects of output format. sprintf is the same as fprintf except that it returns the data in a MATLAB string variable rather than writing it to a file. Sprintf (MATLAB Function Reference) MATLAB Function Referenceįormats 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.
