To read from a file use either the ifstream or fstream object and the name of the file.
Using fstream to load a file into a mat type.
Stream class to both read and write from to files.
Stream class to write on files.
Input output with files c provides the following classes to perform output and input of characters to from files.
Filename can include a file extension and a full or partial path.
The file association of a stream is kept by its internal stream buffer.
If you do not specify filename the load function searches for a file named matlab mat.
Note that we also use a while loop together with the getline function which belongs to the ifstream object to read the file line by line and to print the content of the file.
Objects of this class maintain a filebuf object as their internal stream buffer which performs input output operations on the file they are associated with if any.
File streams are associated with files either on construction or by calling member open.
Name of file specified as a character vector or string scalar.
Dictionary in which to insert matfile variables.
And ifstream object is used to open a file for reading purpose only.
True to append the mat extension to the end of the given filename if not already present.
The data is a sequence of samples.
Name of the mat file do not need mat extension if appendmat true.
These classes are derived directly or indirectly from the classes istream and ostream we have already used objects whose types were.
The from file block icon shows the name of the mat file that supplies the data to the block.
Stream class to read from files.
If the stream is already associated with a file i e it is already open calling this function fails.
The data can be in array format or matlab timeseries format.
Input output stream class to operate on files.
Either ofstream or fstream object may be used to open a file for writing.
Each sample consists of a time stamp and an associated data value.
This is an instantiation of basic fstream with the following template parameters.
Can also pass open file like object.
Opens the file identified by argument filename associating it with the stream object so that input output operations are performed on its content argument mode specifies the opening mode.
If filename has no extension that is no text after a period load looks for a file named filename mat if filename has an extension other than mat the load function treats.
