If the statement executes code or statement block only when the condition is true. MATLAB uses for loops and while loops. This is a three step process: Notice that we need to initialize a loop variable (a while loop does not do this automatically). Commented: Walter Roberson on 11 Oct 2017 What is the syntax of do while loop in matlab? Create the MATLAB program consisting of the MATLAB code of Figure 1 . Hence, it is used to execute code repeatedly as long as a certain condition is met. It is a conditional programming keyword used to give conditions to the program on Matlab. The statements that are executed need to have non-zero elements, and when the condition is false, the loop will stop. The condition may be any expression, and true is any nonzero value. To build the model and generate code, press Ctrl+B. There are several ways of writing a for loop in MATLAB. Somehow, it also works as a break statement. ...
