Input arguments for functions where argument is a structure

How do you input arguments for functions where argument is a structure? The specific example i am trying to use is the MaxIter under the 'options' structure in the svmtrain function.

svmtrain(...., struct('MaxIter', 12345))

or

svmoptions.MaxIter = 12345;
svmtrain(...., svmoptions)
