For a list of common values for the locale, see the Locale name-value pair argument for the datetime function. The writing function ignores the 'DateLocale' parameter value whenever dates can be written as Excel-formatted dates. Writing mode, specified as the comma-separated pair consisting of 'WriteMode' and a character vector or a string scalar. Select a write mode based on the file type.
If the file you specified does not exist, then the writing function creates and writes data to a new file. The writing function does not alter any data outside of the range occupied by the input data. If you do not specify a sheet, then the writing function clears the first sheet and writes the input data to it.
If you do not specify a sheet, then the writing function appends the input data to the bottom of the occupied range of the first sheet. If you do not specify a sheet, then the writing function removes all other sheets from the file, and then clears and writes the input data to the first sheet. If the file you specified does not exist, then the writing function creates a new file and writes the input data to the first sheet.
When WriteVariableNames is set to true , the writing function does not support the write mode 'append'. When the write mode is 'append' , the writing function does not support the Range parameter. If the file you specified does not exist, then the writing function performs the same actions as 'replacefile'. Example: 'WriteMode','append'. Field delimiter character, specified as the comma-separated pair consisting of 'Delimiter' and a character vector or string scalar containing one of these specifiers:.
You can use the 'Delimiter' name-value pair only for delimited text files. Example: 'Delimiter','space'. Indicator for writing quoted text, specified as 'QuoteStrings' and either true or false.
If 'QuoteStrings' is true , then the function encloses text in double-quote characters and replaces any double-quote characters surrounding text with two double-quote characters. The two double-quote characters are also referred to as escaped characters. If 'QuoteStrings' is false , then text is written without alteration. If 'QuoteStrings' is unspecified, the function inspects the data for delimiters designated by the 'Delimiter' name-value argument.
If a delimiter is found within a column, each element within the column will be written with double-quotes. You can use the 'QuoteStrings' name-value argument only with delimited text files. Character encoding scheme associated with the file, specified as the comma-separated pair consisting of 'Encoding' and 'system' or a standard character encoding scheme name.
When you do not specify any encoding, the writing function uses UTF-8 to write the file. Worksheet to write to, specified as the comma-separated pair consisting of 'Sheet' and a character vector or a string scalar containing the worksheet name or a positive integer indicating the worksheet index.
The worksheet name cannot contain a colon :. For more information, see sheetnames. The writing function also generates a warning indicating that it has added a new worksheet. You can use the 'Sheet' name-value pair only with spreadsheet files. Example: 'Sheet' , 2. Example: 'Sheet' , 'MySheetName'. Data Types: char string single double int8 int16 int32 int64 uint8 uint16 uint32 uint Rectangular portion of worksheet to write to, specified as the comma-separated pair consisting of 'Range' and a character vector or string scalar in one of the following forms.
Corner1 specifies the first cell of the region to write. Toggle Main Navigation. Search MathWorks. Open Mobile Search. Off-Canvas Navigation Menu Toggle. Main Content. Syntax fprintf fileID,formatSpec,A1, Open Live Script. Print Double-Precision Values as Integers. Write Tabular Data to Text File. Get Number of Bytes Written to File. Display Hyperlinks in Command Window. Input Arguments collapse all fileID — File identifier 1 default 2 scalar. File identifier, specified as one of the following: A file identifier obtained from fopen.
Identifier Order for processing the function input arguments. Flags '—' Left-justify. Note If you specify a precision operator for floating-point values that exceeds the precision of the input numeric data type, the results might not match the input values to the precision you specified.
Ordinary text to print. Numeric conversions print only the real component of complex numbers. Numeric or character arrays, specified as a scalar, vector, matrix, or multidimensional array. Output Arguments collapse all nbytes — Number of bytes scalar. Create a table T2 which includes row names using the RowNames name-value pair argument.
Export T2 to a tab-delimited text file named tabledata2. Use the Delimiter name-value pair argument to specify a tab delimiter, and the WriteRowNames name-value pair argument to include row names. Use fprintf to export the cell array by specifying the format of the output data. Alternatively, import the cell array using fprintf. Open a file that you can write to named celldata. Define formatSpec using the format specifiers to describe the pattern of the data in the file. Separate each format specifier with a space to indicate a space delimiter for the output file.
