memanggil dan menjalankan fungsi matlab di C#

Untuk beberapa kasus mungkin kita akan membutuhkan komponen untuk menyelesaikan permasalahan yang sedang kita selesaikan, seperti misalnya jika kita ingin menyelesaikan sebuah perhitungan Quadratik pasti akan kesulitan jika tanpa menggunakan komponen, banyak sekali komponen-komponen yang disediakan untuk .NET seperti ACCORD dan AFORGE dua framework ini sangatlah powerfull. tapi kali ini saya akan coba memanggil function matlab dari C#. pada contoh kali ini hanya akan di demokan cara pemanggilan sebuah function yang ada di matlab. pada pengembangannya nanti kita bisa membuat sebuah program di matlab berupa sebuah function dan hasilnya kita tarik ke dalam program .NET C# yang kita buat. Sekarang kita mulai membuat project.
pertama-tama yang harus kita lakukan adalah membuat sebuah function di matlab, walaupun pada dasarnya kita bisa memanggil semua function yang ada di matlab, akan tetapi agar memudahkan dalam pemahaman, kita buat function sendiri.
  • Buka matlab (disini matlab yang digunakan adalah matlab R2012a)
  • Buat sebuah function sederhana di matlab, function inilah yang nanti akan kita panggil di C#. klik file pilih new function pada matlab, setelah itu tambahkan code berikut ini

  • langkah selanjutnya ketikan deploytool untuk menampilkan jendela deployment project di matlab. kurang lebih seperti pada gambar dibawah ini

     Perhatikan pada main jendela deploytool pada matlab, pada kolom project isi dengan nama project yang kita bangun, misalnya kita isi dengan nama "" dan pada kolom type kita pilih .NET Assembly. setelah itu klik button OK. 
  •   Maka akan tampil jendela project dari deployTool seperti pada gambar dibawah ini

  •  klik pada Add class untuk menambahkan class pada project yang kita bangun di matlab. dan juga tambahkan add file dimana add file ini sebenarnya adalah menambahkan letak file fucntion yang kita buat tadi
  • sekarang lakukan proses build dengan melakukan klik icon build di samping project, unntuk lebih jelasnya silahkan perhatikan gambar dibawah ini

    •  jika proses build project sudah complete, maka kita akan mendapatkan dua folder yaitu scr dan distrib. letak kedua folder terletak dimana meletakan function penamnahan matrix.
    • Selanjutnya kita buka project baru di Visual studio (disini versi yang digunakan adalah visual studio 2013 dengan target framework 4.0). klik file new project pada IDE visual studio, pilih windows apllication serta pada kolom name silahkan diisi dengan nama yang diinginkan, klik OK.
    • jika form sudah muncul, tambahkan komponen 3 datagridview dan juga 1 button. atur dan tata sedemikian rupa sehingga interfacenya seperti pada gambar dibawah ini
    •  tambahkan komponen yang kita dapatkan dari build project di matlab. pada kasus contoh ini dll yang terbentuk adalah tambahMatrix.dll (nama file dll ini tergantung dari nama project) dan tambahkan satu componen file dll MWarray.dll berada di folder C:\Program Files\MATLAB\R2012a\toolbox\dotnetbuilder\bin\win64\v2.0. untuk cara menambahkan dll dalam program pilih menu project dan pilih add reference, browse dan cari filenya.
    •  tambahkan reference pada header program.  

    • doouble klik pada button1 untuk membangkitkan event single klik  pada button tersebut, setelah itu tambahkan code program berikut ini

    project done, silahkan di running program.  jika langkah-langkah diatas dilakukan dengan benar maka hasil output seperti pada gambar dibawah ini.
    Hasil running program, saat pertamakali di jalankan program akan tampil seperti pada gambar dibawah ini

    Setelah button Matlab function di klik, hasilnya seperti pada gambar dibawah ini
