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.
Differentiation: The derivative of a function y = f(x) can be written as follows or f '(x) and is defined as the rate of change of the dependent variable y with respe
5 p2+8p+15, 3 p2-3p-18, 12 p2-p-30
Illustration of Logical vectors: Calling the function appears to return similar vector as simply vec > 5, and summing the result still works to determine how many elements wer
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).
Strings as matrix: The matrix can be generated, that consists of strings in each row. Therefore, essentially it is created as a column vector of strings, but the final result
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
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
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
How do I write a product series running from i to n of x''s using a for loop?
Sorting The Sorting is a process of putting a list in order; either in descending (maximum to minimum), or ascending (minimum to maximum) order. For illustration, here is a li
