Constructs
MATLAB provides the for, while and if constructs. MATLAB will wait for you to type the end statement before it executes the construct.
>> y=[];
>> for x=0.5:0.5:5
y=[y,2*x];
end
>> y
>> n=3;
>> while(n~=
0)
n=n-1
end
>> if(n < 0)
-n
elseif (n == 0)
n=365
else
n
end
The three numbers in the for statement specify start, step and end values
for the loop. Note that you can print a variable's value out by mentioning
its name alone on the line. ~=
means `not equal to' and == means `equivalent to'.
