Usage
The while loop executes a set of statements as long as a the
test condition remains true. The syntax of a while loop is
while test_expression
statements
end
Note that a conditional expression is considered true if the
real part of the result of the expression contains any non-
zero elements (this strange convention is adopted for
compatibility with MATLAB).
Examples
Here is a while loop that adds the integers from 1 to 100:
--> accum = 0;
--> k=1;
--> while (k<=100), accum = accum + k; k = k + 1; end
--> accum
ans =
5050
