As alternatives, you also can modify table variables using dot syntax or by indexing into the table. You can add, move, and delete table variables using the addvars, movevars, and removevars functions. This example shows how to add, delete, and rearrange column-oriented variables in a table. Add the first names of the patients as table variables. Add, Delete, and Rearrange Table Variables. Specify the last names of patients as the row names of the tables. A table can have row names along its first dimension, labeling the rows, but is not required to have them. An inner join keeps only those table rows that match with respect to the key variables.Ĭreate two tables of patient data. When you join tables or timetable together using the join, innerjoin, and outerjoin functions, you can specify row labels as key variables.įor example, you can perform an inner join two tables together, using row names and a table variable together as key variables.

When you group rows together using the rowfun, varfun, stack, and unstack functions, you can specify row labels as grouping variables. lut randi (100, 1, 60) value lut (10) get lut value corresponding to index 10.

Therefore, in matlab, a lut is simply your standard array if whatever it is to store in your table is homogeneous and scalar, and a cell array otherwise. Use Row Labels as Grouping or Key Variables In any language, a look-up-table is just an array of whatever things you want to look up.
