Syntax of a two-dimensional array:- arr= array([ [arr1], [arr2] ]) #2 Attributes with two-dimensional arrays:- - dtype attribute returns the data type of the data with which you are working. - ndim attribute gives the number of dimensions of an array and also gives the rank to an array. e.g, if it is a single-dimensional array then it will return 1 if three-dimensional array then it returns 3. It will also give the rank whether it is 1-D, 2-D and many more. - shape attribute returns the number of rows and the number of columns present inside an array. - size attribute gives the size of the entire block. - flatten attribute convert the 2-dimensional array into a single-dimensional array. #3 - reshape attribute is used to change the dimensions of an array. We can convert a 1-D array to a 2-D array by using the reshape method. - reshape(r,c) method takes two parameters ie., the number of rows and a number of columns, that you want in an updated array. - reshape attribute also works with a 3-D array. In 3-D, we have multiple 2-D arrays. And a 2-D array contains multiple 1-D arrays. #4 - Matrices can be defined as a two-dimensional array that has multiple rows and columns. - A matrix that has one row and multiple columns is known as a row matrix. - A matrix having one column and multiple rows is known as a column matrix. - Both the row matrix and column matrix is in the form of a single-dimensional array. - A separate format available for a matrix in python. #5 Functions with matrix:- - matix() attribute is used to convert an array into a matrix format. - We can also create a matrix without using an array. It can also be created directly by using the matrix() attribute. matrix('1 2 3 6 ; 4 5 6 7') In this, values are separated by using the space, and rows are separated by using the semicolon. - A diagonal () function can be used to only print the diagonal elements of an array. - min() function will give the minimum value element from an array. - max() function is used to get the maximum value element of an array. - There is a certain number of rules that should be followed in matrix multiplication.
