Writing to Files:
There are many lower level functions which can write to files. We will focus on the fprintf function that can be used to write a file and also to append to a file.
To write one line at same time in a file, the fprintf function is used. AS similar to the other low-level functions, the file should be opened first for writing and must be closed once the writing has been done. We have, obviously, been using the fprintf to write to the screen. It is the the default output device, therefore if a file identifier is not identified; the output goes to the screen; or else, it goes to the identified file. The default file identifier number is 1 for the screen. The common form is as shown below:
fprintf(fid, 'format', variable(s));
Example of Minimum and Maximum Value For matrices, the functions min and max operate column wise by the default: >> mat = randint(2,4,[1 20]) mat = 9 10 1
Creating Customized strings: There are many built-in functions which create customized strings, including blanks, char, and sprintf. We know that the char function can be u
Concatenation: The String concatenation means to join the strings altogether. Of course, as strings are merely vectors of the characters, the technique of concatenating vector
Strings as Vectors: The Strings are considered as vectors of characters-or in another words, a vector in which each and every element is a single character-so numerous vector
Give the formula for a rational function that has a hole at x=7 & vertical asmptote at x=-3/2
Differentiation: The derivative of a function y = f(x) can be written as follows or f '(x) and is defined as the rate of change of the dependent variable y with respe
Built-in functions for Complex numbers: We know that in MATLAB both i and j are built-in functions which return √-1 (therefore, they can be thought of as built-in constants).
Functions to create special matrices: The MATLAB also has various functions which create special matrices. For illustration, the zeros function generates a matrix of all zeros
Illustration of nested function: The output arguments are distinct from variables. The scope of an output argument is merely the nested function; and it cannot be used in the
Function isreal - complex numbers: The function isreal returns 1 for logical true when there is no imaginary part of the argument, or 0 for false when the argument does have a
