deleteexpvar

  DELETEEXPVAR - Delete a variable from the experiment.mat file in a DIRSTRUCT 

     DELETEEXPVAR(MYDIRSTRUCT,NAMETOBEDELETED)

     Deletes an experiment variable from the DIRSTRUCT given.

     NAMETOBEDELETED can be a single string or should be a cell list of strings of variable names.

     Note that there must be enough memory to read in the entire 
     set of saved variables for the DIRSTRUCT.

     If one also wants to save some new data to the DIRSTRUCT, one can pass additional
     arguments:

     DELETEEXPVAR(MYDIRSTRUCT, NAMETOBEDELETED, ADDITIONALVARS, ADDITIONALVARNAMES, PRESERVE_ASSOCIATES)

     This will delete the variables titled NAMETOBEDELETED, and add variables with names
     ADDITIONALVARNAMES with data ADDITIONALVARS. ADDITIONALVARNAMES and ADDITIONALVARS
     should be cell lists, so that ADDITIONALVARNAMES{i} is the name of the variable whose
     data is ADDITIONALVARS{i}. If PRESERVE_ASSOCIATES is 1, then any associates of MEASUREDDATA objects
     are preserved.  This form is functional equivalent to:
             DELETEEXPVAR(MYDIRSTRUCT,NAMETOBEDELETED);
             SAVEEXPVAR(MYDIRSTRUCT,ADDITIONALVARS,ADDITIONALVARNAMES,PRESERVE_ASSOCIATES);
     but doing this in one step requires much less disk access and is faster.
