Condition expression - while/do-while loop will be an infinite if it is a always TRUE. Skip to content. Rather than forcing the termination from the loop, it moves to the next iteration of the given loop, and it skips any of the codes in between the program. The FOR loop is used when the number of iterations that a set of instructions is to be executed is known. n=100; for i=1:n while … Condition statement - for loop will be an infinite if it is blank. 1. Its initial value is the machine epsilon, the distance from 1.0 to the next largest floating-point number on your machine. MATLAB uses for loops and while loops.
