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.
Function xlsread - file function: The function xlsread will read from the spreadsheet file. For illustration, to read from file just generated: >> ssnums = xlsread('ranexc
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
Common form of the switch statement: The common form of the switch statement is as shown below: switch switch_expression case caseexp1 action1 case cas
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
Illustration of Standard Deviation The less spread out the numbers are, therefore smaller the standard deviation will be, as it is a way of determining the spread of the data.
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).
Creating Customized strings: There are many built-in functions which create customized strings, including blanks, char, and sprintf. We know that the char function can be u
Nested IF-ELSE statements: The if-else statement is used to select between the two statements. In order to select from more than two statements, the if-else statements can als
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
Use of string variables: The Characters involve letters of the alphabet, punctuation marks, digits, white space, and control characters. The Control characters are characters
