Hello,
For one of my automation scripts, I need to extract all the lookup table variable names (I.e., Table Data name, Breakpoint 1, Breakpoint 2,...etc) using MATLAB command.
I can extract the Table data Name only by using below code:
Lkup_Nme_ = find_system(path,'blockType','Lookup_n-D');
So, I am looking the solution in such a way, so that I can get the names of Table data, Breakpoints 1, Breakpoints 2. I.e. abc_Pbar_Zz, abc_Pbar_Xx and abc_A_Yy respectively.

Hi Manish,
I understand that you are looking to extract the lookup table variable names using MATLAB commands. To achieve this, you can utilize the "get_param" command, which allows you to extract the values of block parameters. Here is a sample code snippet for your reference:
mdl = 'name_of_model';
load_system(mdl)
TableDataName = get_param([mdl,'/n-D Lookup Table'],'Table')
Breakpoint1_name = get_param([mdl,'/n-D Lookup Table'],"BreakpointsForDimension1")
Breakpoint2_name = get_param([mdl,'/n-D Lookup Table'],"BreakpointsForDimension2")
Refer to the following documentation for more information on 'get_param':

Hi Lokesh,
There are many lookup table used in the model. For above command, it might be only possible if block handle is known. If I select the block and then try with your command, It will work. But my requirement is to get the name/value of all the available lookup table, by just giving the path.

When there are multiple lookup tables used in the model, you can use 'find_system' to first find all instances of the blocks of interest and then iterate over them to extract the desired parameters.
Refer to this code snippet:
lookupTableBlocks = find_system('model_name', 'BlockType', 'Lookup_n-D');
for i = 1:length(lookupTableBlocks)
% Extract block-specific parameters
TableDataName = get_param(lookupTableBlocks{i},'Table');
Breakpoint1_name = get_param(lookupTableBlocks{i},"BreakpointsForDimension1");
Breakpoint2_name = get_param(lookupTableBlocks{i},"BreakpointsForDimension2");
% Display or store the extracted information
fprintf('Block: %s\n', lookupTableBlocks{i});
fprintf('Table Data Name: %s\n', TableDataName);
fprintf('Breakpoint 1 Name: %s\n', Breakpoint1_name);
fprintf('Breakpoint 2 Name: %s\n', Breakpoint2_name);
% You might want to store these in an array or cell array for later use
end
