Note the following rules when using for loops with the loop variable expression k = m:s:n • The step value s may be negative. Example: k = 10:-2:4 produces k = 10, 8, 6, 4. • If s is omitted, the step value defaults to 1. • If s is positive, the loop will not be executed if m is greater than n. • If s is negative, the loop will not be executed if m is less than n. • If m equals n, the loop will be executed only once. • If the step value s is not an integer, round-off errors can cause the loop to execute a different number of passes than intended. 4-25 Z.R.K
The continue Statement The following code uses a continue statement to avoid computing the logarithm of a negative number. x = [10,1000,-10,100]; y = NaN*x; for k = 1:length(x) if x(k) < 0 continue end y(k) = log10(x(k)); end y The result is y = 1, 3, NaN, 2. Z.R.K 4-26 More See pages 210-217.

Note the following rules when using for loops<br />
<strong>with</strong> the loop variable expression k = m:s:n<br />
• The step value s may be negative.<br />
Example: k = 10:-2:4 produces k = 10, 8, 6, 4.<br />
• If s is omitted, the step value defaults to 1.<br />
• If s is positive, the loop will not be executed if m is<br />
greater than n.<br />
• If s is negative, the loop will not be executed if m<br />
is less than n.<br />
• If m equals n, the loop will be executed only once.<br />
• If the step value s is not an integer, round-off<br />
errors can cause the loop to execute a different<br />
number of passes than intended.<br />
