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 for strings, %d for integers, and %f for floats. The function textscan reads text data from a file and stores it in the cell array. The fgetl and fgets functions both read the strings from a file one line at a time; the dissimilarity is that the fgets holds the newline character when there is one at the end of the line, while the fgetl function gets rid of it. All these functions at first need opening the file, and then closing it when terminated.
As the fgetl and fgets functions read one line at a time, such functions are usually in some form of a loop. The fscanf and textscan functions can read the whole data file into one data structure. In terms of the level, these two functions are somewhat in between the load function & the lower level functions like fgetl. The file should be opened by using fopen first, and must be closed by using fclose afterward the data has been read. Though, no loop is needed; they will read in the whole file automatically but into the data structure.
Index vector: The index vector is then used as the indices for original vector. To get grades vector in ascending order, the indices used would be grades (2), grades (5), and
Example of Mode When no value appears more often than any other, the smallest value in the vector will be the mode of the vector. >> shortx = [2 5 1 4]; >> mode(shortx
Functions which return Values versus printing: Also, the function which computes and returns values (throughout the output arguments) does not generally print them; that is le
Introduction and Purpose In the lectures and tutorials you have been introduced to a number of probability distributions. You have also learned that modelling any system (such

Illustration of Indexing into vectors of structures: For illustration, the function to print the information from packages has been modified therefore in addition to the vecto
Illustration of reading from files: For illustration, suppose that there is a data file 'subjexp.dat' that has on each line a number followed by thecharacter code. The type fu
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',.
Logical Built-In Functions: There are built-in functions in the MATLAB which are useful in conjunction with vectors or matrices of all logical true or false values; two of the
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
