In this situation, the data is missing. Read the page Missing Data in MATLAB.
You can't leave an element empty, but you can fill it with a missing value. MATLAB will then place the appropriate value for the data type. Use the function missing.
  • double, single, duration, and calendarDuration convert missing to NaN
  • datetime converts missing to NaT
  • categorical converts missing to <undefined>
  • string converts missing to <missing>

Depends on what you're going to do with the data. Maybe you should just delete the row. Maybe you should set the missing values to 0 or nan. Maybe you want to call fillmissing(). Tell us what you think you should do once you hit that row of the table. What are you doing with all the other, valid rows in the table?

ı put ''NaN'' at not given values. because in the fillmissing() ı should write a method, dimention or constant.
