strcspn

lengths from the beginning of texts until a character among those prohibited

res = strcspn(Strings, forbiddenChars)

Strings: 文字列または文字列の行列
forbiddenChars: 文字列または文字列の行列
res: Matrix of positive real integers, of the size of Strings: lengths of the selected Strings heads.

res = strcspn(Strings, forbiddenChars)は, Stringsの中で forbiddenCharsの一部の文字のどれかが最初に現れる位置を探し,それが最初に現れるまでのStringsの文字数を返します.

forbiddenCharsの次元がStringsと同じ,またはforbiddenCharsが文字列である必要があります.

strcspn("fcba73", "1234567890")
strcspn(["fcba73", "f7cba73"], "1234567890")
strcspn(["fcba73", "f7cba73"], ["312", "34567890"])

strspn — lengths of the beginning of strings as long as characters are among those allowed
