FOR LOOP (DO LOOP) for m = 1 : 10 (calculations) m is a counter to track the number of passes through the calculations. a = 0 for m = 1:10; m a = a + m pause end pause command stops the program and waits for user to press a key. Useful to monitor the values of the variables.

Matlab codes: FOR LOOP EXAMPLE for i = 1 : 11 x(i) = (i-1) * (2*pi/10) ysin(i) = sin(x(i)) clear variables plot ysin vs. x clear for i = 1:11; x(i) = (i-1) * (2*pi/10); ysin(i) = sin(x(i)); end plot (x,ysin)

WHILE LOOP (calculations) Condition true? No while [condition] (calculations) - a counter variable is not required. - must contain a logical condition to control the looping.
