title: Matlab strsplit by space and quotes
body: <p>I have a string of variable names as shown below:</p>
  
  <pre><code>{'"NORM TIME   SEC, SEC, 9999997" "ROD FORCE, LBS, 3000118" "ROD   POS, DEG, 3000216" P_ext_chamber_press P_ret_chamber_press "GEAR#1 POS INCH" 388821 Q_valve_gpm P_return 3882992 "COMMAND VOLTAGE VOLT"'}
  </code></pre>
  
  <p>the double quotes are for the variable names with spaces or special characters between the words" and a single word variable doesn't have any quotes around them.  The variables are separated by one space.  Some variable names are just numbers.</p>
  
  <p>At the end, I want to create a cell with strings as follows:</p>
  
  <pre><code>{'NORM_TIME_SEC_SEC_9999997','ROD_FORCE_LBF_3000118','ROD_POS_DEG_3000216','P_ext_chamber_press','P_ret_chamber_press','GEAR#1_POS_INCH','3388821','Q_valve_gpm','P_return','3882992','COMMAND_VOLTAGE_VOLT'}
  </code></pre>
