code:

s=sprintf([sim_filename '/L_%d'],Loads_new_to_Loads_old_index(i,2));
add_block('mylibmodels/Single_phase_Var_Load', s)
set_param(s,'P', act_power_of_loads(1,i));
set_param(s,'Q', react_power_of_loads(1,i));

error:

Invalid setting in SubSystem block (mask) 'L_6' for parameter 'P'

The two arrays that i want to extract from them their values to set them as parameters in the blocks, are arrays with numbers only. Thank you

This is a small part of my code. The 'sim_filename' is define above this code. The problem is in the function set_param i believe. Thank you

Most block parameters, even though they are numeric to the user, are strings when getting from get_param(). So when setting the parameters, you also need to provide the string.

Just run get_param() first to see what type you get and then provide the similar. Use num2str(), mat2str() if needed.
