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.
Polynomials: Simple curves are polynomials of various degrees, or orders. The degree is the integer of the highest exponent in the expression. The illustrations are as follows
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.
Vectors of nested structures: The Combining vectors and nested structures are possible to have a vector of structures in which several fields are structures themselves. Here i
WHILE Loops: The while statement is used as a conditional loop in MATLAB; it is used to repeat an action whenever ahead of the time it is not known how many times the action w
