Lower Level File I/O Functions:
Whenever reading from data file, as long as the data in the file is "regular" the load function works-in another words, the similar type of data on every line and in the similar format on every line-therefore it can be read into a matrix.
Though, data files are not always set up in this manner. Whenever it is not possible to use the load, MATLAB has what are known as lower level file input functions which can be used. The file should be opened first, that involves finding or creating the file and positioning an indicator at the starting of the file. Whenever reading has been done, the file should be closed.
Likewise, the save function can write matrices to the file, but when the output is not a simple matrix there are lower level functions to write to files. The file once again should be opened first and closed when the writing has been done.
Illustration of Indexing: Though, rather than of creating the index vector manually as shown here, the process to initialize the index vector is use to a sort function. The al
Reading from Files: There are many lower level functions which read from files. The function fscanf reads the formatted data into a matrix, by using conversion formats like %s
Core Objects: The Core Objects in MATLAB are the very fundamental graphics primitives. The description can be found under the MATLAB Help: Under the Contents tab, click the Ha
Advanced File Input and output: Where 'format' involves the conversion characters much like those used in the fprintf function. For illustration, to read the file 'subjexp.dat
Location of a rectangle - graphics objects: The location of a rectangle is [x y w h], where x and y are the coordinates of the lower left point, here w is the width, and h is
Representing Logical true and False: It has been stated that expressions which are theoretically true really have the integer value of 1, and expressions which are theoretical
Opening and Closing a File: The Files are opened with the fopen function. By the default, fopen function opens a file for reading. If the other mode is preferred, a permission
Statistics There are numerous statistical analyses which can be executed on data sets. In MATLAB software, the statistical functions are in the data analysis help topic known a
Vectorizing: In most of the cases in MATLAB, loops are not essential. As MATLAB is written specifically to work with the vectors and matrices, most operations can be completed
