MATLAB: Model Compilation Through M-Script

MATLABmodel compilesimulink

My question is I got 36 models(all in slx format) present in structure array under the field 'name'.My Objective is to compile each model one after another through M-script
The script I written is as below
sort_slx_files = dir('*.slx'); The models are present in the directory
for i = 1:length(sort_slx_files)
load_system(sort_slx_files(i).name)
(sort_slx_files(i).name([],[],[],'compile'));
end
But I get the error 'Index exceeds matrix dimension'
How to resolve this error and get the objective of compiling the models one after another

sort_slx_files(i).name is a string, that is the cause of the error.
use eval([sort_slx_files(i).name,'([],[],[],''compile'');']);
