2.编程：

xOffset = 1;

if (nargin==2) || ...

(nargin==3 && ischar(varargin{3})) || ...

(nargin==4 && (~ischar(varargin{4}) || strcmp(varargin{4}, 'extrap')));

end

% Process Y in INTERP1(Y,...) and INTERP1(X,Y,...)

y = varargin{1+xOffset};

siz_y = size(y);

% y may be an ND array, but collapse it down to a 2D yMat. If yMat is

% a vector, it is a column vector.

if isvector(y)

if size(y,1) == 1

% Prefer column vectors for y

yMat = y.';

n = siz_y(2);

else

yMat = y;

n = siz_y(1);

end

ds = 1;

prodDs = 1;

else

n = siz_y(1);

ds = siz_y(2:end);

prodDs = prod(ds);

yMat = reshape(y,[n prodDs]);
