Zaman karmaşıklığını azaltarak Matlab'daki bir dizgeden ingilizce grafikler nasıl formüle edilir?

Question

Matlab'da fonem dönüşümü için grafikte çalışıyorum ve söz konusu sözcükleri ilk olarak belirli bileşenlere, digraflara ve bunlarla ilgili sesli harflere bölmek için daha genelleştirilmiş bir kod üretmeye çalışıyorum ve her bir girilen dizeyi (sözcük) grafeme biçimine ayırın Böylece daha sonra uygun fonetik sentezi üretebilir. Ancak, çok sayıda kuralın varlığı ve dolayısıyla büyük miktardaki if-elseif-else'den dolayı, her bir harf ve büyüyen dizilerin varlığıyla döngü yaparak, zaman karmaşıklığı manifoldunu arttırmış ve herhangi bir sonuç vermemiştir , her zaman konsoldan bir string girişi giriyorum). Bana kodu basitleştirmek yardım lütfen olabilir Yani eğer, burada aşağıda verilmiştir:
