Fortran90アレイは空白値をヌルとして読み取ります

Question

私は外部テキストファイル（30行、7列）を読み込みますが、各行は "、"で区切られています。私は、 ",,"と表現されている欠けている値があります。 2次元配列にデータを読み込むと、欠損値は0.00で置き換えられますが、データにも0.00値があります。私が平均を計算しているとき、カウント（アイテム数（n））はカウントされます - （欠損値の数）。どのようにして欠損値を動的に選ぶことができますか？

Answer 1

あなたのデータに負の値を持っていないように見えます、どのように 'を置換ところ、FORTRANにデータを渡す前に、いくつかの前処理を行うことについて,,」負の値で、

sed 's/,,/,-1,/g' 

と、たとえば次に簡単にあなたのFortranプログラムでこれらの無効なデータを識別することができますし、それに応じてそれを扱う。
