Error Expression or statement is incorrect - ,-possibly
unbalanced L {", or t.
Here MATLAB is confused with the list of variables because a list within
parentheses represents matrix indices. When the variables represent output
of a function or a list of vectors, they must be enclosed within square brackets.
The correct command here is [x , y] =circlefn (5) ( circlefn is a user-written
function) . When parentheses and brackets are mixed up, the same error message
is displayed:
» (x,y] = circlefn (S) ;
??? (x,y] -circlefn (S) ;

3.
>> X 1:10;
» v [0 3 6) i
»X(v)
??? Subscript indices must either be real pos itive integers
or logicals.
The first element of the index vector v is zero. Thus, we are trying to get the
zeroth element of x. But zero is not a valid index for any matrix or vector
in MATLAB except when it is a logical zero (i.e., zeros produced by logical
operations) . The same problem arises when a negative number appears as an
index. Also, of course, an error occurs when the specified index exceeds the
corresponding dimension of the variable:
»X (12)
??? Attempted to access x(12) ; index out of bounds because numel (x) =l O .
The examples given here for index-dimension mismatch are almost trivial.
Most of the times, these problems arise when matrix indices are created, incremented,
and manipulated inside loops.
