Use of logical vector:
Determine how many elements in the vector vec were greater than 5, the sum function can be used on the resulting vector isg:
>> sum(isg)
ans =
3
The logical vector isg can also be used to index into the vector. For illustration, when only the elements from the vector which are greater than 5 are preferred:
>> vec(isg)
9 6 11
As the values in the vector should be logical 1's and 0's, the below function which appears at first to accomplish the similar operation by using the programming method, really does not. The function receives 2 input arguments: the vector, and an integer with which to compare (therefore it is somewhat more common). It loops through each element in the input vector, and stores the result vector either a 1 or 0 based on whether vec(i) > n is true or false.
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
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).
User input in the while loop: Here is an illustration of running this script: >> readonenum Enter a positive number: -5 Invalid! Enter a positive number: -2.2
The variance is generally defined in terms of the arithmetic mean as: At times, though, the denominator is defined as n instead of n - 1. The default definition used by t
Function fopen - file function: The permission string in the call to the fopen function identifies that the file is opened for writing to it. Just as when reading from a file,
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
Illustration of logical built-in functions: The function find returns the indices of a vector which meet certain criteria. For illustration, to find all the elements in a vect
fprintf function - File function: The fprintf function really returns the number of bytes which was written to the file, therefore if you do not want to see that number, suppr
Changing Dimensions: In addition to transpose operator, the MATLAB has some built-in functions which change the dimensions or configuration of matrices, involving fliplr, resh
Logical Vectors: The relational operators can also be used with the vectors and matrices. For illustration, let's say that there is a vector, and we want to compare each eleme
