Switch
The basic form of a
switch
statement is:
switch
test
case
result1
statements
case
result2
statements
.
.
.
otherwise
statements
end
The respective
statements
are executed if the value of
test
is equal
to the respective
result
s. If none of the
case
s are true, the
otherwise
statements are done. Only the first matching case is carried out. If
you want the same
statements
to be done for different
case
s, you can
enclose the several
result
s in curly brackets:
switch x
case 1
disp('x is 1')
case {2,3,4}
disp('x is 2, 3 or 4')
case 5
disp('x is 5')
otherwise
disp('x is not 1, 2, 3, 4 or 5')
end
While
The basic form of a
while
loop is
while
test
statements
end
The
statements
are executed repeatedly while the value of
test
is
equal to 1. For example, to find the first integer
n
for which 1+2+
ยทยทยท
+
n
is is greater than 1000:
n=1;
while sum(1:n)<=1000
n = n+1;
end
