Consider using my IQML (IQFeed-Matlab) connector for this. IQML enables both synchronous (blocking) and asynchronous (background) queries for multiple symbols, that are fetched either serially or in parallel (using the Matlab Parallel Computing Toolbox). A simple usage example:

>> data = IQML('history', 'symbol','AAPL', 'dataType','ticks')
data =
  100×1 struct array with fields:
    Symbol
    Timestamp
    Datenum
    Last
    LastSize
    TotalVolume
    Bid
    Ask
    TickID
    BasisForLast
    TradeMarketCenter
    TradeConditions
    TradeAggressorCode
    DayOfMonth
    BasisDescription
    TradeMarketName
    TradeDescription
    AggressorDescription

>> data(end)
ans =
                  Symbol: 'AAPL'
               Timestamp: '2019-10-04 09:45:03.862626'
                 Datenum: 737702.406294699
                    Last: 224.67
                LastSize: 100
             TotalVolume: 5226196
                     Bid: 224.66
                     Ask: 224.68
                  TickID: 7432
            BasisForLast: 'C'
       TradeMarketCenter: 19
         TradeConditions: '01'
      TradeAggressorCode: 0
              DayOfMonth: 4
        BasisDescription: 'Last qualified trade'
         TradeMarketName: 'Nasdaq Trade Reporting Facility (NTRF)'
        TradeDescription: 'Normal Trade'
    AggressorDescription: 'Unknown/unsupported'

IQML was developed with top performance, reliability and usability in mind. IQML supports 100% (repeat: 100%) of IQFeed's API functionality. It is fully documented, continuously maintained/improved, and I am happy to provide support.
