Hello,

I am trying to build a script to extract data from a model. In this case I need to extract data from Lookup tables.

Using find_system with 'BlockDialogParams' I can find all the referenced variables inside blocks, but I cannot know which ones they are. Namely in lookup tables, I would like to know which variable is X, Y, table, etc.

Is there a way to extract this information from the block via command?

Thanks in advance.

for Lookup tables: get_param(Path, 'Table') and get_param(Path,'InputValues')

and for Lookup2D and others: get_param(Path, 'Table'), get_param(Path, 'RowIndex') and get_param(Path, 'ColumnIndex')

get_param(Path,'InputValues') gives this error. Lookup_n-D block does not have a parameter named 'InputValues'. Please guide

For example, set_param(FullBlockPath, 'Table','rand(5,5)');

web(fullfile(docroot, 'simulink/slref/block-specific-parameters.html#mw_bcbf0db9-99c3-49db-b165-cbaa8e19fa2d'))
