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 flipud functions flips up to down. Note that in these illustrations mat is unchanged; rather than, the results are stored in the default variable ans each time.
The rot90 function rotates the matrix counter clockwise 90 degrees, therefore for illustration the value in the top-right corner becomes rather than the top-left corner and the last column becomes the first row:
>> mat
mat =
14 61 2 94
21 28 75 47
20 20 45 42
>> rot90(mat)
ans =
94 47 42
2 75 45
61 28 20
14 21 20
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).
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
Function xlsread - file function: The function xlsread will read from the spreadsheet file. For illustration, to read from file just generated: >> ssnums = xlsread('ranexc
Illustration of Spreadsheet Files: This reads the numbers in a double vector variable nums and the text in a cell array txt (the xlsread function forever returns the numbers f
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
Three-Dimensional Plots: The MATLAB has many functions which will display three-dimensional plots. Most of these functions have similar name as corresponding two-dimensional p
Strcat function - Concatenation : The strcat function, though, will eliminate the trailing blanks from strings before concatenating. Note that in these illustrations, the trail
Complex numbers: A complex number is commonly written in the form z = a + bi here a is known as the real part of the number z, b be the imaginary part of z, and i is √-1
Customizing Plots : There are numerous ways to customize figures in the Figure Window. On clicking the Plot Tools icon will bring up the Property Editor & Plot Browser, with ma
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
