Advanced File Input and Output:
In that section, we saw how to read the values entered by user using the input as well as the output functions disp and fprintf, that shows information in windows on the screen. For file input and output (file I/O), we used the load and save the functions, that can read from a data file into the matrix, and write from a matrix to a data file. We also saw that there are three various operations which can be performed on files: reading from files, writing to files (implying writing to the starting of a file), and appending to a file (that is writing to the end of the file).
There are many different file types that use dissimilar filename extensions. Faraway, using load and save, we have worked with files in the ASCII format that usually use either the extension .dat or .txt. The load command works only if there are similar number of values in each line and the values are of similar type, so that the data can be stored in a matrix; the save command writes only from the matrix to a file. When the data to be written or file is to be read in a different format, then the lower level file I/O functions should be used.
The MATLAB software has functions which can read and write data from variousfile types like spreadsheets; usually Excel spreadsheets have the filename extension .xls. It has its own binary file type also that uses the extension .mat.
These are generally known as MAT-files, and can be used to store the variables which have been generated in the MATLAB.
Example of sorting strings: To sort a cell array of strings, also the sort function is used. The illustration is as follows, >> engcellnames = {'Chemical','Mechanical',.
Steps for input output functions - Lower level file: The steps involved are as shown below: Open the file. Read the file, write to the file, or append to the file.
Run-time or execution-time error: The Run-time, or execution-time, errors are found whenever a script or function is executing. With most of the languages, an illustration of
#qYou will need to examine two of the nine sections of data: one section of qualitative data (choose either Gender or Position) one section of quantitative data (choose either Intr
Illustration of Median When the vector is not in sorted order to start with, the median function will still return the right answer (it will sort the vector automatically). For
The IF Statement: The if statement selects whether or not the other statement, or group of statements, is executed. The common form of the if statement is as shown below: i
Data structure layers: There are many layers in this variable. For illustration, cyls is the whole data structure, that is a vector of structs cyls(1) is a separate
Example of Core objects: The one core graphics object is a line that is also what the plot function produces. Here is an illustration of generating a line object, altering som
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
Nested for Loops: The action of a loop can be any of the valid statement(s). Whenever the action of a loop is the other loop, this is known as nested loop. As an illustrati
