How do I write a script for the MATLAB code?

 Scripts are the simplest kind of program file because they have no input or output arguments. They are useful for automating series of  MATLAB commands, such as computations that you have to perform repeatedly from the command line or series of commands you have to reference.

You can create a new script in the following ways:

• Highlight commands from the Command History, right-click, and select Create Script.
• Click the New Script button on the Home tab.
• Use the edit function. For example, edit new_file_name creates (if the file does not exist) and opens the file new_file_name. If new_file_name is unspecified, MATLAB opens a new file called Untitled.

After you create a script, you can add code to the script and save it. For example, you can save this code that generates random numbers from 0 through 100 as a script callednumGenerator.m.

columns = 10000;
rows = 1;
bins = columns/100;

rng(now);
list = 100*rand(rows,columns);
histogram(list,bins)
