What is the Matlab command to create a vector of the even whole numbers between 29 and 73?

Nana76 [90]3 years ago

Answer:

x = 29:73;

x_even = x(2:2:end);

Explanation:

In order to create a vector in Matlab you can use colon notation:

x = j:k

where <em>j</em> is 29 and <em>k</em> is 73 in your case:

x = 29:73

Then you can extract the even numbers by extracting the numbers with even index (2,4,6,etc.) of your vector:

x_even = x(2:2:end);

In the line of code above, we define <em>x_even</em> as all the elements of x with even index from index 2 till the end index of your vector, and an increment of 2 in the index: 2,4,6,etc.

If you want the odd numbers, just use the odd indices of your vector:

x_odd = x(1:2:end);

where <em>x_odd</em> contains all the elements of <em>x</em> with odd index from index 1 till the end index, and an increment of 2: 1,3,5,etc.

Character positions in<br> arrays start counting with<br> the number 1.<br> True<br> False
d1i1m1o1n [39]

Answer:

False.

Explanation:

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.

In Computer programming, an array can be defined as data structure which comprises of a fixed-size collection of variables each typically holding a piece of data and belonging to the same data type such as strings or integers.

This ultimately implies that, when a programmer wishes to store a group of related data (elements) of the same type, he or she should use an array.

Generally, character positions in arrays start counting with the number 0 not 1.

Hence, an array uses a zero-based indexing and as such the numbering or position of the characters (elements) starts from number 0. Thus, the first character (element) in an array occupies position zero (0), the second number one (1), the third number two (2) and so on.
