UseCache	Use Dataset that has already been cached	[True, False]	boolean	False	no

Examples

In this example, it is assumed that the dataset spar.ds contains S-parameters at frequencies of 1 and 2 GHz.
S11Var=dsexpr("S(1,1)", "spar.ds")
returns a dataset variable containing S(1,1)
S11A=dstoarray(S11Var)
returns an array of S(1,1) value

Notes/Equations

The dsexpr() function executes a simulation expression on the dataset and returns the results as a dataset variable, which can be processed further to access the required data. If the dataset has already been accessed before and has been cached, then the cached value can be accessed by setting the UseCache argument as True.
