Nonfinite endpoints or increment for colon operator in index.

hi, cant help me with this error?

i cant see this message: "Nonfinite endpoints or increment for colon operator in index."

the error is in the line "Error in sexto (line 90)

    frame  = x(curPos:curPos+windowLength-1);   % get current frame:"

this is my code:

i cant see this message: "Nonfinite endpoints or increment for colon operator in index." the error is in the line "Error in sexto (line 90) frame = x(curPos:curPos+windowLength-1);

Well, did you verify whether curPos and curPos+windowLength-1 are finite as the error message prompted you?
