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
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
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
