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 illustration, the below will generate a 5 × 3 matrix of arbitrary integers, and then write it to a spreadsheet file known as the 'ranexcel.xls' which has five rows and three columns:
>> ranmat = randint(5,3,[1 100])
ranmat =
96 77 62
24 46 80
61 2 93
49 83 74
90 45 18
>> xlswrite('ranexcel',ranmat)
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
Standard Deviation The standard deviation is the square root of variance: The built-in function in a MATLAB for the standard deviation is known as std; the standard dev
Example of Logical built-in functions: For equivalent to all the function, we should make sure that the entire elements in the vector are logically true. The one way of doing
Minimum and Maximum Value The MATLAB has built-in functions for numerous statistics. For illustration, min and max to find the minimum or maximum value in a data set. >> x
Plot Functions: Faraway, we have plotted to generate two-dimensional plots and bar to generate bar charts. We have seen how to clear the Figure Window by using clf, and how to
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
If I have a vector representing the packed storage form of a symmetric matrix, how do I perform a cholesky factorisation on that?
how can reconstruct just part of an image using imreconstruct?
Creating string Variables: The string consists of a few numbers of characters (including, possibly, none). These are the illustrations of the strings: '' 'x' 'ca
Program of built-in factorial function: Calling this function yields similar result as the built-in factorial function: >> fact(5) ans = 120 >> factorial(
