Try for exception handling cc4m_logo_inline
IDSTAT-18
TitleOnly use the try construct for exception handling.
PriorityStrongly recommended
Severity level5
DescriptionOnly use the try construct for exception handling.
An exception object must be assigned or created and an error function must be called in the catch.
Do not use try/catch to suppress errors or to express simple conditions.
There are other, more suitable options for that.
RationaleUsing try for simple error suppression can result in poor performance and unexpected behaviour. When a different error occurs than the one expected, it can go undetected because of the try/catch.

Avoid:

try
    nElems = container.nElements;
catch
    nElems = 0;
end

Instead use:

if isfield(container, 'nElements')
    nElems = container.nElements;
else
    nElems = 0;
end
