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
Using Functions with the Vectors and Matrices: As MATLAB is written to work with the vectors and matrices, the whole vector or matrix can be passed as an argument to the funct
Illustration of a recursive function: illustration is of a recursive function which does not return anything, but simply prints. The below function prtwords receives a sentenc
bar and barh functions: For a matrix, the bar and barh functions will group altogether the values in each and every row. The illustration is as shown: rm = randint(2,4,[1
Writing and Reading Spreadsheet Files: The MATLAB functions xlswrite & xlsread will write to and read from the spreadsheet files which have the extension .xls. For illustratio
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
Illustration of Empty vectors: The Empty vectors can also be used to delete elements from the arrays. For illustration, to remove the third element from array, an empty vector
Plot types: Besides plot and bar, there are another plot types like stem plots, histograms, stem plots, area plots and pie charts, and also other functions which customize the
Illustration of Labels and prompts: The program below prompts the user for endpoints (x1, y1) and (x2, y2) of a line segment, and computes the midpoint of the line segment, th
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
Fliplr function: The fliplr function "flips" the matrix from left to right (in another words the left-most column, the first column, become the last column and so on), and the
