MROWS를 지정할 경우, NCOLS도 지정해야 합니다. 유효하지 않은 데이터형입니다. 첫 번째 인수는 double형, single형, int8형, uint8형, int16형, uint16형, int32형, uint32형 또는 논리형이어야 합니다. 희소 배열은 지원되지 않습니다. The length of the DCT-I transform must be greater than 1. Use a longer transform length or a different variant of the DCT. The length of the DCT-I transform must be greater than 1 in every dimension. Use a longer transform length or a different variant of the DCT. Transform length must be a nonnegative integer scalar. Unrecognized option; specify the transform type with 'Variant' followed by an integer between 1 and 4. Transform variant must be an integer scalar between 1 and 4. Transform output size must have at least NDIMS elements. Transform output size must be a real integer row vector. Transform output size vector must contain non-negative integers.
