Indexed empty matrix:
The Individual elements cannot be eliminated from matrices, as matrices always have the similar number of elements in every row.
>> mat = [7 9 8; 4 6 5]
mat =
7 9 8
4 6 5
>> mat(1,2) = [];
??? The Indexed empty matrix assignment is not permitted.
Though, whole rows or columns could be removed from a matrix. For illustration, to remove the second column:
>> mat(:,2) = []
7 8
4 5
Counting in a While Loop: Whenever it is not known ahead of the time how many values will be entered into the script, it is often essential to count the number of values which
Types of User-defined Functions: We know how to write a user-defined function, stored in an M-file, which computes and returns one value. This is merely one type of the functi
Referring to and Modifying the Matrix Elements: To refer to matrix elements, the row and then the column indices are given in parentheses (always the row index initially and t
Functions to create special matrices: The MATLAB also has various functions which create special matrices. For illustration, the zeros function generates a matrix of all zeros
Writing to Files: There are many lower level functions which can write to files. We will focus on the fprintf function that can be used to write a file and also to append to a
5 p2+8p+15, 3 p2-3p-18, 12 p2-p-30
Matrix of Plots: The other function which is very useful with any type of plot is subplot that creates a matrix of plots in the present Figure Window. The three arguments are
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
If I have a vector representing the packed storage form of a symmetric matrix, how do I perform a cholesky factorisation on that?
Find Minimum and Maximum for each row To find the maximum (or minimum) for each row, the dimension of 2 (that is how a MATLAB refers to rows) can be identified as the third arg
