Igor Proは単純なデータ処理、グラフ描画だけではなく、自分でスクリプトを書く事によってデータの入出力、様々な加工・統計処理、グラフ処理までを自動で行うことが可能である(実際Igor Proのメニューのコマンドもスクリプトで行われている)。

基本操作

プログラミングの基礎

先程のスクリプトにグラフの描画機能を加えたもの

スペース、tab, commaなどで区切られた2つのデータファイルを基にスペクトル、差スペクトルの描画を行います。

Igor Proで動作する波長(wave length)と波数を相互に変換する単純なマクロです。

Raman shiftをnm(またはその逆)に変換するために作りました。

プロシージャファイルにコピーしてコンパイルして使ってください。
