Flow Control

break

The bre ak statement lets you exit early from a for loop or while loop. In

nested loops,

break exits from the innermost loop only.

Here is an im provement on the example from the previous section. Why is

this use of

break a good idea?

a = 0; fa = -Inf;

b = 3; fb = Inf;

while b-a > ep s*b

x = (a+b)/2;

fx = x^3-2*x-5;

if fx == 0

break

elseif sign(fx) == sign(fa)

a = x; fa = fx;

else

b = x; fb = fx;

end

Error Control – try, catch

This section covers those MATLAB functions that provide error handling

control.

try

The general form of a try-catch statement sequence is

try

statement

...

statement

catch

statement

...

statement

end
