A true expression has either a logical true or nonzero value. For nonscalar
expressions, (for example, “if (matrix A is less than matrix B)”), true means
that every element of the resulting matrix has a logical true or nonzero value.
Expressions usually involve relational operations such as (count < limit) or
isreal(A). Simple expressions can be combined by logical operators (&,|,~) into
compound expressions such as: (count < limit) & ((height - offset) >=
0).

Examples In this example, if both of the conditions are not satisfied, then the student fails
the course.
if ((attendance >= 0.90) & (grade_average >= 60))
pass = 1;
else
fail = 1;
end;
