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). The Complex numbers can be generated by using i or j, for illustration, 5 + 2i or 3 - 4j. The multiplication operator is not needed between the value of the imaginary part and the constant i or j.
The MATLAB also has a function complex which will return a complex number. It receives two numbers, that is the real and imaginary parts in that order, or only one number that would be the real part (therefore the imaginary part would be 0). Here are a few illustrations of generating complex numbers in a MATLAB:
>> z1 = 4 + 2i
z1 =
4.0000 + 2.0000i
>> z2 = sqrt(-5)
z2 =
0 + 2.2361i
>> z3 = complex(3,-3)
z3 =
3.0000 - 3.0000i
>> z4 = 2 + 3j
z4 =
2.0000 + 3.0000i
>> z5 = (-4) ^ (1/2)
ans =
0.0000 + 2.0000i
>> myz = input('Enter a complex number: ')
Enter a complex number: 3 + 4i
myz =
3.0000 + 4.0000i
Note that even when j is used in an expression, i is used in the outcome. The MATLAB displays the type of the variables generated here in the Workspace Window (or by using whos) as double (complex). The MATLAB has functions real and imag which return the real and imaginary parts of complex numbers.
>> real(z1)
4
>> imag(z3)
-3
Creating string Variables: The string consists of a few numbers of characters (including, possibly, none). These are the illustrations of the strings: '' 'x' 'ca
Illustration of Writing to files: Here is the other illustration in which a matrix is written to a file. At First, an arbitrary 2 × 4 matrix is generated, and then it is writt
Recursive Functions: The Recursion occurs whenever something is defined in terms of itself. In the programming, a recursive function is a function which calls itself. The Recu
Built in recursive function in MATLAB: We have seen that the built-in function in MATLAB to compute factorials, termed as the factorial and we know how to implement the iterat
strvcat function - concatenation: The function strvcat will concatenate it vertically, that means that it will generate a column vector of the strings. >> strvcat(fir
Writing variables to a File: The save command is used to write variables to a file, or to append the variables to a MAT-file. By the default, save function writes to a MAT-fil
Types of User-defined Functions: We know how to write a user-defined function, stored in an M-file, which computes and returns one value. This is merely one type of the functi
Labels and Prompts: The script loads all the numbers from file into a row vector. It then splits the vector; it stores the initial element that is the experiment number in a v
Refer the subset of a matrix: It is also possible to refer to the subset of a matrix. For illustration, this refers to the first & second rows, second & third columns: >> m
Write a MATLAB function [d1, u1, l1, c1, r1] = NaiveGaussArrow(d, u, l, c, r) that takes as input the 5 vectors dened above representing A. This function performs Naive Gauss redu
