How do you run a while loop if a=10 and b=100 and c=.1, where when 'a' and 'b' are more than 'c' apart, it will divide 'a' by 1.2 and 'b' by 2.2, so they change every time. There are two types of nested loops in MATLAB. When nesting a number of while statements, each while statement requires an end keyword. Otherwise, the expression is false. MATLAB uses for loops and while loops. If our for loop began for x = 1:2:15, we must state that x = 1 initially, before our while loop begins.

You can programmatically exit a loop using a break statement, or skip to the next iteration of a loop using a continue statement. What is the syntax for do while loop in matlab? To skip the rest of the instructions in the loop and begin the next iteration, use a continue statement. The initial value assigned to a is 2. To execute statements if any element is true, wrap the expression in the any function. 1. WHILE loop syntax: The condition is usually a comparison of a variable to a constant. The FOR loop is used when the number of iterations that a set of instructions is to be executed is known.
