Hi Harish,
As per my understanding you are trying to set the block parameters programatically.
You can use "set_param" function for this case as follows:
% here block_path is the path to your toWorkspace block in your model
set_param(block_path, 'MaxDataPoints', 'inf'); %set the Limit data points to last to inf
set_param(block_path, 'SaveFormat', 'Timeseries'); %set the save format to Timeseries
Hope this resolves your query!
