Writing variables to a File:
The save command is used to write variables to a file, or to append the variables to a MAT-file. By the default, save function writes to a MAT-file. It can either save the whole present workspace (all variables which have been generated), or a subset of the workspace (involving, for illustration, just 1 variable). The function save will save the file in the present directory, therefore it is important to set that properly first.
To save all the workspace variables in a file, the command is as shown below:
save filename
The .mat extension is automatically added to the filename. The contents of the file can be exhibited by using who with the -file qualifier:
who -file filename
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
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
bar and barh functions: For a matrix, the bar and barh functions will group altogether the values in each and every row. The illustration is as shown: rm = randint(2,4,[1
How do I write a product series running from i to n of x''s using a for loop?
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
fprintf function - File function: The fprintf function really returns the number of bytes which was written to the file, therefore if you do not want to see that number, suppr
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
Illustration of Minimum and Maximum Value Both of these functions also return the index of the minimum or maximum value; when there is more than one occurrence, it returns the
Minimum and Maximum Value The MATLAB has built-in functions for numerous statistics. For illustration, min and max to find the minimum or maximum value in a data set. >> x
Symbolic Expression The solve function solves an equation and returns the solution(s) as symbolic expressions. The answer can be converted to numbers by using any numeric funct
