FoldingMatrix[sequence,k]⟹matrix

this function takes a sequence and returns a matrix descirbing if the ovelapping subsequenes of length k from start to finish could fold onto eachother where 1 specifies a posible fold, and 0 specifies no fold.

FoldingMatrix[sequence,k,Span[m,n]]⟹matrix

this function takes a sequence and returns a matrix descirbing if the ovelapping subsequenes of length k in the range from position m to n could fold onto eachother where 1 specifies a posible fold, and 0 specifies no fold.
