replace each inports of a simulink model at the root level by constant blocks typed in matlab

main.m
% Define the model name
modelName = 'myModel';

% Load the model
load_system(modelName);

% Get all the blocks in the model

% Loop through the blocks
for i = 1:length(blocks)
    % If the block is an Inport block, replace it with a Constant block
