And, if you are completely new to programming then as well you need not worry as the discussions in this article is at absolute beginner level and you are not required to have a programming background. Based on the condition provided, a while loop can run for a finite number of times producing finite output or it can go for as long as possible unless stopped manually. What it means is that the while loop will run till the value of a is less than 20. MATLAB is developed by MathWorks and in order to use it, one must purchase a license. HDL Code Generation Generate Verilog and VHDL code for FPGA and ASIC designs using HDL Coder™. You can programmatically exit a loop using a break statement, or skip to the next iteration of a loop using a continue statement. Try typing flag just after having started Matlab and you will see a non-empty matrix appearing. The outer loop might loop through the rows and the inner loop through the columns for example. do % Not valid MATLAB syntax statements while … A number has been loaded in variable 'n' with the help of command written in line-4.This number also has been copied in variable 'factorial'.Condition written in line-6 will operate until n is greater than 1.A decrements of number is must in 'while' loop so that while condition may become false after some time otherwise program may go into infinite loop.
