fopen function - file function:
The fopen opens the file for reading. The fscanf then reads each line one double and one character, and put each pair in individual columns in the matrix. The dimensions identify that the matrix has two rows, by though many columns are essential (equivalent to the number of lines in the file). As matrices store the values which are all of similar type, the characters are stored as their ASCII equivalents in the character encoding (example, 'a' is 97). This matrix has been once created; it may be more helpful to separate the rows into vector variables and to convert the second back to characters, that can be completed as shown below:
>> nums = mat(1,:);
>> charcodes = char(mat(2,:))
charcodes =
abaab
Obviously, the results from fopen and fclose must be checked but were absent here for the simplicity.
Use of function polyval: The better the curve fit, the more exact these interpolated and extrapolated values will be. By using the subplot function, we can loop to display the
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
Areacirc function: The areacirc function can be called from the Command Window as shown here, or from a script. Here is a script which will prompt the user for the radius of o
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 dat
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
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
Rectangle - graphics objects: The other core graphics object is the rectangle that can have curvature added to it (!!). Merely calling the function rectangle without any argum
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
