سپس کلید پکیج  را زده تا پکیج مورد نظر آماده شود. دقت داشته باشید که بعد از انتخاب کامپایلر متلب، حجم پکیج نزدیک به 400 مگابایت خواهد شد. پکیج مورد نظر بصورت یک فایل exe فشرده خواهد شد.
معمولا پکیج شامل فایل‌های زیر باید باشد :

بعد از طی مراحل فوق نوبت به تیم برنامه‌نویسی دات نت می‌رسد. بعد از دریافت پکیج از تیم برنامه‌نویسی متلب در صورتیکه بر روی سیستم هدف کامپایلر متلب و یا خود متلب نصب نیست باید از داخل پکیج این کامپایلر نصب شود.
دقت داشته باشید که ورژن کامپایلر بر روی سیستم باید با ورژن پکیج دریافتی یکی باشد.
در VS یک پروژه کنسول ایجاد کنید و از فولدر پکیج پروژه دریافتی در زیرفولدر distrib فایل makeSqr.dll را به رفرنس برنامه VS اضافه کنید.
در ادامه از مسیر نصب کامپایلر فایل MWArray.dll را هم به رفرنس پروژه اضافه کنید. این فایل جهت تبادل داده اپلیکیشن با کامپایلر متلب مورد استفاده قرار می‌گیرد.
